You could stuff a very densely pack amount of pillow stuffing into a tube and maybe make an actual suppresser. I don’t want the fbi showing up at my door so I won’t try it lol
You used a Desert Eagle because a revolver bleeds noise and gasses out of the cylinder gap which makes makes suppression pretty much pointless. Just like Archie and Rifles mentioned before me.
A Nagant revolver is also cool, as the 7 round cylinder goes forward a little bit, to seal it, and allow suppresors. Thats also why the cartridges look so weird, in order to allow an air tight seal.
Clarifications on the video: fact 1: The Vector system is the one I took the animation of. That system is patented, and has different advantages, being shorter than traditional actions and with eliminated barrel rise. It is definitely a good design. But you cannot do anything against the linear momentum of recoil: what happens is that when the bolt carrier is forced downwards, it transfers its backwards impulse to the gun. At the end of the cycle, once rest is reached, the shooter will have received an amount of backwards impulse exactly equal to that of the bullet and propellant gases, but in the opposite direction. A closed system, like a gun after it has fired, will keep its overall momentum until an external force acts upon it, no matter what happens inside it. It is the same reason why a moving astronaut will not stop until it hits something, no matter how he moves his arms and legs. The topic is analysed more in depth here: ua-cam.com/video/MJfmfesfg3E/v-deo.html fact 2: different people can aim slightly differently, but the effect of this on accuracy, or group size, is negligible (unless they haven't been told how to aim of course). Sometimes the shots group position can be slightly affected, which is the reason why zeroing the sights is slightly dependent on the shooter. In any case, the discrepancies due to aiming are one order of magnitude smaller than those due to trigger pulling, especially with handguns. fact 3: *edit: the noise levels measured are all lower than the true peaks, since the meter had a time weighting too long to measure the actual impulse value, and what is shown is a noise level averaged over 125 ms. fact 4: there's no phosphorus whatsoever fact 5: unless it is badly designed, or the material is flawed, dry firing a centerfire gun is safe. The reason is that the energy provided by the spring is relatively small, at around 1 Joule, and spread over the relatively large surface of the firing pin (or hammer) body, so the impact is not unlike the bolt of a semiautomatic rifle hitting its endstop, it just won't exceed the design stresses. Some modern guns, including glocks, even require dryfiring in order to field strip. There may be some (rare) weak design, but generally there's no need to worry.
alright im maybe about to get a lot of hate here possibly since this video has so many likes but.... idk man.... someone can correct me if i'm wrong here "fact" #1 getting less recoil with the same round? "you cannot do anything against the linear momentum of recoil" then you literally talk right after about muzzle breaks which do just that, by redirecting exhaust gasses outwards to the side and make the barrel take the load and not the person shooting, and you say gun design basically can't do anything? there are counter balance systems like the AK-107 which when firing has a gear that controls a counterweight to fly forward which negates almost all the recoil, Now idk man i would think that if most of the "recoil force" is going into a counterweight going forwards instead of back into the shooter would count against the "backwards impulse" the shooter feels "fact" #2 some people have better "aim" than others? the "aim" here is the noun version which is "the directing of a weapon or object at a target." Um.... idk how to break this to you.... But yes some people have better aim, i don't think my grandma who's never fired a gun and has arthritis would compete against a sniper, even with corrective eye-wear, hell even if she didn't have arthritis and has the same steady hands and eyes as the sniper.... STILL wouldn't have as good of "aim" cause she probably wouldn't know how to zero in, or lead targets. "fact" #3 something something pillow... "silent" Obviously no one is going to believe or think "oh... a pillow will 100% negate all sound coming from a firearm" it should be whether or not the sound is lowered to something more respectable and i would say for the glock to be 92.8 decibels.... something like a 22 pistol would be even lower than that..... and something like a blender is usually around 90 decibels and unless you live in an apartment you've probably never heard someone else's blender go off, i'd say that it "silences" it pretty well idk this whole thing is like the whole suppressor vs "silencer" thing "fact" #4 tracer rounds have NO phosphorus whatsoever? BOIIIII the first incendiary rounds to ever exist in ww1 were essentially tracer rounds and were called "smoke tracers" as they ignited not on impact but as soon as fired and GUESS WHAT THEY USED PAL PhOsPhOrUs ua-cam.com/video/0T63jaXjh9o/v-deo.html "fact" #5 bro honestly.... this might be the only thing that's "right" in this video.... But because everything else i think was wrong.... unless im wrong.... Im gonna say this is wrong too and you should never dry fire a gun
but yeah most modern tracers don't use phosphorus, getting less recoil with same mass and powder bullet or whatever that beginning claim is obviously not true, anyone who practices enough shooting and acquires *_knowledge_* can get good "aim" or rather everyone can have good "aim" assuming they dont have arthritis and they're not literally blind, and pillows obviously don't fully silence a gun in case anyone thinks im disagreeing with EVERYTHING cause im not.
@@BladezAndrew Thanks for your extensive comment, and for suggesting interesting reasoning inputs, mainly regarding recoil. Regarding which, I'd like to explain something in a little more detail: If one system, composed by one or more interconnected bodies, like a firearm, expels some of its mass with a given velocity, (in our case the bullet and propellant gases), it will start moving in the opposite direction with a velocity that only depends on the mass of the system, the expelled mass, and the velocity at which it is thrown. In particular, the linear momentum of the system will be exactly the same as that of the bullet and propellant gases, and the center of mass of the system will keep moving at that same velocity until an external force acts upon it. So now I have my complex system, or firearm, going backwards, and let's say for simplicity that it is free floating in space. If I now move a counterweight inside the firearm, towards the back, I could actually get the rest of the firearm to stop moving at all... but not for very long! If I want my firearm to remain in one piece, the counterweight will reach an endstop at some point, and transfer back the momentum to the rest of the firearm, bringing us to the starting point. In fact, with this trick I didn't even change the velocity of the center of mass at all! What I did is simply create an unbalance, or oscillation, of the system. But if all of this is true, then what's the purpose of the AK 107 and similar systems? In automatic firearms, a raciprocating mass is already present, the bolt carrier group, so I already have a source of oscillation. I can use my counterweight to cancel out the oscillations at all. This is very helpful for full auto firing, but is not eliminating recoil, just the shaking due to the reciprocating mass! And in fact, in the AK 107 the counterweight is thrown forward instead of backward, to counteract the effect of the bolt carrier that is going backwards. So is there something that can be done to actually reduce recoil momentum? Yes, but at a cost: for every momentum you throw forward, you've got to throw the same behind. So either you throw less mass forward, or you throw some backwards. A muzzle brake easily accomplishes the first task: it strips the exhaust gases and throws them perpendicular to the barrel, eliminating their contribution to recoil momentum. I can do even better: I can design the muzzle brake to throw the gases backwards, and actively counteract the recoil, but to an extent: The mass of the gas is usually insufficient to compensate all of the recoil. So if I want to reduce recoil even more, I have to increase the charge, and vent a large part of it backward. I have just made a RECOILLESS gun. So in conclusion, once you have fit the best possible muzzlebrake, there is nothing else you can do to reduce recoil momentum, you can only increase the time over which it is transferred to the shooter, to make it less annoying. Regarding the tracers, in the video I meant flame tracers, the ones that are commnoly used. The smoke tracers based on phosphorus were in fact built in a controlled atmosphere and specific handling was used in manufacturing, as is the case for incendiary WP weapons And regarding the pillow silencer... I must admit that I did that mainly for the thumbnail, unfortunately that's how youtube works nowadays.
Your take on physics in general is correct... But there's a lot of complicated mechanics going on in each firearm the add to the overall recoil impulse. Since guns use springs and moving parts, the impulse after the gun goes off has multiple variables. Different timings and mechanical processes make things not so cut-and-dry as your simple High School physics equal and opposite reaction conclusion. If you study about moment of impact with energy and momentum if you change the timing and duration of the event you can't get much different results with the same original force. Yes a given ammo will always generate the same force back into the gun and shooter, but how each gun deals with that force is different. not just whether or not it has a compensator. That's why a certain AR-15 firing the same ammo will have different felt recoil then another one. So your point is very basic and overlooks all the complicated things that might actually tell you about how the guns going to recoil.
Better suppression on that pillow if used lengthwise. However, I don't think people are walking around with pillows in their pockets just on the off chance you have to assassinate someone. The idea behind the 'myth' is probably that it's a suppressor of opportunity, when you just forgot to pack the right tools as professionals often do. As long as you slow the expansion of gasses and spread it to a wider area, the report is going to be quieter and probably won't sound as much of a gunshot. Better yet, wrap that pillow around your favorite killing knife on your hitman gigs. Tbh this isn't even a myth but something a screenwriter came up with. A lazy one at that. Academically thinking it can work. However most (proper) pistols won't even fire if the slide isn't forward all the way and you shouldn't use a pistol if you can get that close. Also a fire hazard!!!!
Per either of the two standards of metering cans, you can get something along the line of 25-30 for any standard size centerfire rifle can. The pillow thing works if the question is “does it make it quieter?” But not necessarily “do they work as well as suppressors?” Or “do they silence the gun?” And thank you for pointing out how loud 95 decibels still is.
I think there’s 2 reasons for using a pillow to shoot someone in the movies, it makes it a bit quieter, yeah still loud, but imagine in a hotel, it could stop it traveling to other rooms as noticeably, but I think the other reason is because the shooter won’t get any blood splash back on them! I’ve also seen it done in the films with a silenced pistol so it probably wouldn’t be that loud from a silenced gun through a pillow? Anyway cool vid 👍🏻
That would do nothing as far as slowing down a bullet. If there is any difference in the math, it is minimal at best..... unless the pillow was more than a foot think of dense material. So realistically speaking, a foam pillow would little effect on slowing a bullet since the super hot gases in front of the bullet would melt the foam. If it was down feathers, maybe that would change things. However, its all in the math. You might have something on the blood splatter though. Lat time I did that without the pillow, it got on everything. I was forever cleaning brain matter out of crevasses and pockets.....
Yeah, the main movie I remember seeing this done is The Good, The Bad, and The Ugly, where The Bad moved a pillow over someone's face before shooting him a couple times. I don't even think he put the barrel up to the pillow. It might also be used for some characterization, too. The Bad seemed cold and uncaring when he put the pillow over that guy's face, like he didn't even care enough to look into the eyes of the person he was about to kill; but I can also see it being used to show someone's cowardice or lack of resolve, not wanting to see the person they're about to end.
@@rherman9085 I think that he meant the SOUND would be less likely to travel to other rooms, as it would be muffled twice, once by the pillow, and then by the walls.
A well-made wall between two hotel rooms sits around 54 dB of noise reduction. So you'd still hear a 94 dB shot, but actually a 40 dB noise passing is not that much (whether it goes unnoticed or not is mainly due to other noises covering it). I was actually surprised by the 10 dB reduction, that's a lot! But the main reason it would be useful are the splatters; a silencer fares quite better than that. Or, to be super silent, you could use just the pillow...
I destroyed one of my father's two Hi-Standard .22 mag over-under two-shot Derringer pistols dry firing it only a few times during a cleaning session...oof...I'll always read up on which firearms can and cannot be safely dry-fired henceforth...
He probably needs the hammer you really can't drop the hammer on empty unless it's not a hammer and it's a firing pin there is internal hammers exposed hammers
@@dwsperspectiveonreality.659 Really? I've been doing it for 40 years. As long as it's a quality made rifle or pistol it's fine. Even a 1935 sears 22 rifle I can do that and it's fine. Right after cleaning that's the last step before I put it away. I've shot many bricks through that rifle.
The pillow thing is to prevent entry wound blood splatter from getting on the shooter. ( assuming close contact with a pistol, not a rifle) more so than for silencing the shot.
The pillow works like a traditional suppressor in that it provides a semi closed system where the gasses can expand slower and less violently prior to being vented into the surrounding atmosphere.
I love how you remained "tuned" on English when you were dismantling the spring of the air rifle. I would have expected a word with a couple of "z" instead of the "f" word
I know that this only Applies to few Situations, but for around here many just load a snapcap as the Last round because they are afraid of firing pin breakage.
The decibel reduction is actually impressive. People don’t realize that dB’s are a logarithmic scale so the difference in 5-10 dBs is super substantial to the human ear
@@andreas6002 I don’t think you’re familiar first hand with subway cars and/or firearms. A subway car going by is substantially quieter than a gunshot when compared apple to apples (I.e. the noise in the subway will carry on substantially longer in duration when compared to a singular gun shot).
@@Morningstar_Actual i get that but look it is not going to have a high impact on the sound of a small explosive, people will still be able to hear it clearly from very far away
Revolvers or well, most of them that don't use a particular system (unlike the nagant) have gaps where the gasses quit, not only something that may render the gun unsuppressable, but also dangerous if your hand is next to/over the cylinder's end
(Paraphrased) "Adding a muzzle brake will reduce recoil, and also adds weigh which doesn't reduce recoil, but does reduce the perceived recoil." On High School Rifle Team (Yes, I'm that old), my favorite was one named "Big Bertha." She was the heaviest lady we had, at 23 pounds. And a .22 caliber bolt action.
Blood splatter mainly occurs at the exit wound (if there is one) which is on the opposite side, but I guess a large pillow would still help shield from any backsplash . Wrapping the whole target head in multiple layers of duvet would probably work better.
Something salient about the pillow "silencer", and silencers in general: Silencers in general don't silence the shot like you see in movies, they just make it quieter. The dB scale is logarithmic, so while you measured a 10dB reduction in noise, that is actually 3.3x quieter.
The noise from the gun come from 2 factors: 1. The gas expanding 2. the bullet breaking the sound barrier (sonic boom). So putting a pillow might effect the first factor but not the second.
Bsa airguns recommend that you dry fire them rather than trying to de-cock the action as it can damage the cocking lever or bend the barrel. Pre-charged air guns are fine to dry fire but also fine to decock by holding the bolt back and letting it go forward slowly like Dr-cocking a firearm hammer.
The pillow silencer was done when criminals used 38 specials, a weak gun by modern standards but they used hollow point bullets way less than we do now, and solid bullets have better penetration. The frequency of sound determines whether it goes through walls, so to test this properly you need to measure the sound from another room. At the time that myth was popular, people usually had a Radio on fairly loud in their house. People nowadays have a TV on a lot of the time, so you will have to find out the average volume of a TV to get an idea of how well this could work in a real-world scenario. Also, the closest person in the building could have several walls between him and the gunshot, and a pillow could easily make up the difference between hearing and not hearing it.
I've sheared off tips of firing pins before from dry firing centerfire weapons. "ultracompact" 380/9mm pistols seem to be the most susceptible to this.
Fun fact while pillows really only dampen the gunshot, it does in fact stop blood splatter from hitting you at close range. While also preventing you from seeing their face which makes it a little easier to pull the trigger. That and you won’t have to see the back of their head popping open like a ripe watermelon.
While Recoil may not be diminished, Muzzle Flip can be reduced with the proper parts. The 'Glock Store' sells Tungsten guide rods for Glock handguns which substantially reduces felt recoil and muzzle flip. Mine works GREAT !
You picked the desert eagle because when the round is fired there is only one way for the gas to escape, but with a revolver the gas escapes out the cylinder
Recoil CAN be mitigated. There is HOW LONG it takes the force to act on you. If you are using a single-shot, then you get the FULL recoil impulse at once. If you use some sort of semi-automatic, then some of the force will go towards moving the bolt back, which will spread out the recoil in time, as the spring begins to take up pressure. This can make the shot more comfortable.
>lower discomfort That is the point of lowering recoil, it makes it easier to handle the recoil, drawing it out instead of making it a single quick pulse, and makes it more controllable. They don't reduce recoil, but they make it more bearable, and in turn you get a very similar effect like a muzzle break, when combined it can make a very distinct difference in shooting the gun.
Let's face it though... the pillow thing was always more about containing the blast and preventing the target's insides from splashing back on the shooter. Keeps things tidy.
I'm guessing you chose the deagle because if you used most other pistols with the same cartridge (which are mostly revolvers) a lot of the gases would go out the sides of the cylinder gap. But with the deagle, all the gas goes out the barrel and it would have more of a possibility to have the pillow suppress more of the gases and therefore more of the noise.
The pillow myth is still a myth because it's usually shown to drop the sound down to a whisper. The truth, as you have demonstrated, is that the sound of the gun is reduced somewhat. But the gun is still pretty loud. The same situation with suppressors. They work, to some degree, but nothing like what is shown in the movies.
Well done! BTW, subscribers, this is the second gun channel I’ve come across this morning where the notifications were turned off. Must have happened in some update? I’ll be going through all my channels this weekend to see which ones got shut off. Remember: UA-cam is not your friend.
A pillow would also help with blood spatter at close range. In John Wick there is a scene of the character Perkins holding a pillow over someone's face then uses a revolver. She uses a pillow to avoid the spray.
The way you have the pillow folded over, I wonder whether having the gun stuck in the middle of the pillow fold would make it quieter because there's pillow material all around it.
A CZ52 pistol, which is chambered in 7.62x25, should never be dry fired. The pistol has a cast firing pin and is easy broken with one or two dry fires. The automatic pistol does have a decocker though and hardened machined aftermarket firing pins are available which are safe to dry fire.
Pillows do work very well at suppressing noise from long guns, as long as they are not semi-auto or revolving cylinder. A .22 rifle is quieted to almost nothing (quieter than a pellet gun) from being fired with the muzzle held firmly against a soft target. I tested this with bolt action, pump, lever action, and semi-auto long guns, and a revolver handgun. I assume the revolver would act the same way in a long gun configuration, it's not significantly quieted, and the semi-auto is much quieter, but not as much as the pump, lever, and bolt guns. Haven't tried break action, but they should be just as quiet as manual action repeating rifles, even in pistol configuration.
Muzzleloading revolvers if properly adjusted can be dry fired because the hammer should not touch the nipples if no cap is installed. If you don't adjust them like just about everyone does, you end up ruining the nipples and having problems when removing the spent caps. You also get better precission if the hammer does not touch the nipple because the end of travel is much softer with the copper absorbing some of the force
I have to wonder if a different type of pillow, such as a down pillow, would have a significant effect on the sound of the weapon firing. I'd have tried a few different pillows, see which dampens the noise the most.
Shooting through a pillow is not to muffle the sound but to stop the back splatter of blood, bone and brains. A blanket or jacket works just as well. Or so I've been told :)
I have seen this type of thing in action. If there is a larger target against it, like the ground, or I guess a living thing, it significantly reduces the noise. Much more so if it is a locked breech firearm such as a bolt action. I know from shooting trapped animals at contact distance with a .22, it can even be quieter than a suppressor.
One of the folks at my long range shooting club insists on putting a snapcap into his Remington 700 rifles. His reason being that if you dry fire the firing pin edges that retains it inside the bolt will experience too much force if there is nothing for the firening pin to slow it down. But in my opinion it's pointless since the pin is made out of pretty strong material that can withstand hitting primers all the time
Some hammer fire pistols can have part breakages due to dry firing, typically the part breaking being the firing pin retaining pin. Not a catastrophic failure, or dangerous, but annoying, and deactivating.
Not something that most people will have to worry about, but dry firing crew-serve weapons (M249, M240B, M2, etc.) can damage the bolt carrier over time. You can still technically dry fire it, however you shouldn't let the bolt ride forward on it's own, instead just ride the charging handle forward so the bolt doesn't slam.
About myth 5. Some centerfire rifles, especially Mauser style rifles, have a lot of vibration transmitted through the firing pin. This can lead to fracturing, I have seen like new and functional firing pins have the tip break with a few dry fires without the firing pin show external damage. Just something interesting I found, maybe a disclaimer to throw in the video
Not just centerfire rifles. Some older shotguns can also break the firing pin tip from dry firing- and single action revolvers with fixed firing pins on the hammer like the one demonstrated in the video. It usually takes a lot of dry firing to break anything, though. What happens is that the tip of the firing pin comes in tension against inertia when the pin or hammer is stopped hard against steel. Thin, small things like firing pin tips are a bit tricky to heat treat correctly, so especially in older guns the firing pin tip has a tendency to be brittle and prone to developing material fatigue. What holds up fine in compression in normal firing may break when dry fired and it gets under tension instead.
I saw someone ignite a 7.62 Nato tracer bullet by moving the protective cover over the tracer material, so you can ignite them by exposing to air. This guy had the burn on his fingers to prove it.
I knew tracers were like small road flares because I pulled a .50 BMG tracer and lit it after I removed the thin copper(?) disc at the base of the bullet. When lit it with C-ration matches I burned my fingers. Road flares burn at nearly 3,000 degrees F, and the tracer may have been that hot too for a couple of seconds. All I know for sure is that it was painful and discolored my burning skin, but not as bad as a fireworks accident years later.
The pillow is used purely as a preventative measure, to stop blood and brains splashing on the executioner, as already pointed out in a previous comment.
Sealed chamber is why you chose the Desert Eagle. Where you would normally have a cylinder gap, from which you you would have a higher sound signature of gas expanding across the gap.
The CZ 52 pistol in 7.62×25mm has a brittle firing pin and it will break if the gun is dry fired. I was hit in the face by the rear end of the firing pin of a CZ 52 that had broken. The broken firing pin was propelled backwards by the recoiling slide. Fortunately, I was not injured.
The reason someone uses a pillow is not to silence the round it is to prevent blood blowing back on the shooter surely. No point in messing up a good suit unnecessarily is there.
I've heard that older revolvers that have a swinging firing pin mounted on the hammer can also break if dry fired too much. I don't know how true that is, I just try to always have snap caps in my guns if I'm dry firing them.
maybe different kinds of pillow stuffing have different effects? like foam, cotton, wool, feathers? movies seem to favor pillows with feather or cotton filling.
Dry firing, I have always understood, that anything with a “firing pin” dry fired causes excessive vibrations in the pin, which can cause cracks in the pin.
You can damage some center firing guns by dry firing. Modern Military, Police or self defence guns are pretty much immune that is true. But particulary with older hunting guns it is possible to loose the tip of the firing pin when dry firing. The firing pin tips are very hard and the shock from hitting the end stop is often enough to just snap the tip clean off the rest of the firing pin. Generally these guns are not designed to be dry fired and even deformation of some parts of the firing pin can occur getting it stuck in the firing pin channel.
Dry firing a Auto 5, or an equivalent like Luigi Franchi ARC, or Verney Carron ARC (who they are centerfire gun btw) will quickly damage and break the firing pin
Pillows are actually used to avoid an assassin getting spattered with his victims blood in point blank shots to the head, thus getting tagged with incriminating forensic material. It does leave burn marks from the shot to the pillow, but the first event is more highly avoidable. There are more readily available and more efficient ways to moderate the sound of gunfire, (silencers), since the decision to kill an individual has been already taken.
I once fired a felt cleaning wad only through my 15 joule spring air rifle, at a thick piece of wrought iron (an excavator bucket tooth tip) and it made a supersonic crack, vanished in a mist of white, and left a dent in the steel. The gun was very unhappy and the spring was badly warped 😕
Give yourself a high friction grip on the pistols by wrapping your support hand around your strong hand so that your support hand knuckles (from the inside) are parallel with your strong hand knuckles. Practice that for an hour a day, everyday. Your thumb should be aligned with your index finger as they both lay along the receiver snd you should feel a slight strain in your forearm running from your support hand thumb and back. You'll get use to it, its just a bit of stretching and it doesnt have any negative affects.
10 decibels of noise reduction is quite a lot in reality. Going back to the recoil impulse, the major part of recoil on a semi-automatic firearm is the reciprocating bolt or slide. The Recoil of actually firing the projectile is minimal.
Retest the pillow one - because here the test is conducted as though the target, Mr Pumpkin, isn't in a bed, you're just using the pillow as a supressor. The myth as used in tv and film is generally where the target, here, Mr Pumpkin, is lying in a bed and so the trajectory of the round(s) fired through the pillow aren't going to exit the target's head into open air, but also go through the bedding. So perhaps retest, with Mr Pumpkin lying in a bed, his head on a pillow, and you use a second pillow as the supressor? :D
Thanks for the vid; I actually learned a few things! However, I'm don't agree that dry firing compressed spring air rifles will always damage them. I've had a .177 break-barrel air rifle since 1974 and have dry fired it many, many times and the rifle still shoots perfectly well. Mine is a single cock type; that is, you open the barrel and cock the spring by pulling the barrel down once. It is not a pump type where you can pump it more than once though. I'm sure you're correct and that many air rifles would be damaged but I'm just saying "not all of them". Perhaps you can investigate and do a video on why it's not a problem for some?
Great video. I do have some observations. 1) Dry firing causes slight overtravel of firing pin that would ordinarily be limited and cushioned by the the softer primer cup when round is present. Peening of firing pin in channel or cratering around firing pin opening on frame, especially of lower quality metals occasionally occurs. 2) When discussing suppressors, you used self loading pistols. I would be curious if you'd use a single shot pistol like a Thompson-Center, pushing tightly against pillow and pumpkin, essentially forcing gasses into pumpkin for cooling and dissipation. What kind of reduction would you get? 3) You've mentioned doing something on strange munitions, on another video. How about examination and commentary on the Soviet PSS pistol, with cartridge that contains all the blast gases, none dissipating to atmosphere. The Russian language videos demonstrating these seem like only sound is mechanism. Will be looking forward to your next video.
Most modern centerfires can be dry fired but avoid it with old ones. The metallurgy was not a precisely controlled and the firing pin might not be hardened perfectly. The shock of a dry fire could break it which leads to the second reason: getting replacement parts. It's not a big deal if replacements are readily available but those from decades ago whose manufacturers are out of business might be a big problem. You could turn your classic into a paperweight.
You used the Deagle to avoid the gasses bleeding out of the cylinder gap like they would on a revolver. Anyways great video!

good job! I will have to make harder riddles
Nice.
what does the pillow do to the gas system?
Tbh, I can’t use an automatic, I have this bad habit of twisting my elbow to dampen the recoil, bad for an automatic, but perfect for a revolver
Great information, I'm surprised the pillow actually silenced the 9mm that much.
You should try doing the same with your 338 Lapua😂
You could stuff a very densely pack amount of pillow stuffing into a tube and maybe make an actual suppresser. I don’t want the fbi showing up at my door so I won’t try it lol

A Nagant revolver is also cool, as the 7 round cylinder goes forward a little bit, to seal it, and allow suppresors. Thats also why the cartridges look so weird, in order to allow an air tight seal.

In any case, the discrepancies due to aiming are one order of magnitude smaller than those due to trigger pulling, especially with handguns.
fact 3: *edit: the noise levels measured are all lower than the true peaks, since the meter had a time weighting too long to measure the actual impulse value, and what is shown is a noise level averaged over 125 ms.
fact 4: there's no phosphorus whatsoever
fact 5: unless it is badly designed, or the material is flawed, dry firing a centerfire gun is safe. The reason is that the energy provided by the spring is relatively small, at around 1 Joule, and spread over the relatively large surface of the firing pin (or hammer) body, so the impact is not unlike the bolt of a semiautomatic rifle hitting its endstop, it just won't exceed the design stresses. Some modern guns, including glocks, even require dryfiring in order to field strip. There may be some (rare) weak design, but generally there's no need to worry.
alright im maybe about to get a lot of hate here possibly since this video has so many likes but.... idk man.... someone can correct me if i'm wrong here
"fact" #1 getting less recoil with the same round? "you cannot do anything against the linear momentum of recoil" then you literally talk right after about muzzle breaks which do just that, by redirecting exhaust gasses outwards to the side and make the barrel take the load and not the person shooting, and you say gun design basically can't do anything? there are counter balance systems like the AK-107 which when firing has a gear that controls a counterweight to fly forward which negates almost all the recoil, Now idk man i would think that if most of the "recoil force" is going into a counterweight going forwards instead of back into the shooter would count against the "backwards impulse" the shooter feels
"fact" #2 some people have better "aim" than others? the "aim" here is the noun version which is "the directing of a weapon or object at a target." Um.... idk how to break this to you.... But yes some people have better aim, i don't think my grandma who's never fired a gun and has arthritis would compete against a sniper, even with corrective eye-wear, hell even if she didn't have arthritis and has the same steady hands and eyes as the sniper.... STILL wouldn't have as good of "aim" cause she probably wouldn't know how to zero in, or lead targets.
"fact" #3 something something pillow... "silent" Obviously no one is going to believe or think "oh... a pillow will 100% negate all sound coming from a firearm" it should be whether or not the sound is lowered to something more respectable and i would say for the glock to be 92.8 decibels.... something like a 22 pistol would be even lower than that..... and something like a blender is usually around 90 decibels and unless you live in an apartment you've probably never heard someone else's blender go off, i'd say that it "silences" it pretty well idk this whole thing is like the whole suppressor vs "silencer" thing
"fact" #4 tracer rounds have NO phosphorus whatsoever? BOIIIII the first incendiary rounds to ever exist in ww1 were essentially tracer rounds and were called "smoke tracers" as they ignited not on impact but as soon as fired and GUESS WHAT THEY USED PAL PhOsPhOrUs ua-cam.com/video/0T63jaXjh9o/v-deo.html
"fact" #5 bro honestly.... this might be the only thing that's "right" in this video.... But because everything else i think was wrong.... unless im wrong.... Im gonna say this is wrong too and you should never dry fire a gun
but yeah most modern tracers don't use phosphorus, getting less recoil with same mass and powder bullet or whatever that beginning claim is obviously not true, anyone who practices enough shooting and acquires *_knowledge_* can get good "aim" or rather everyone can have good "aim" assuming they dont have arthritis and they're not literally blind, and pillows obviously don't fully silence a gun in case anyone thinks im disagreeing with EVERYTHING cause im not.
@@BladezAndrew Thanks for your extensive comment, and for suggesting interesting reasoning inputs, mainly regarding recoil.
Regarding which, I'd like to explain something in a little more detail: If one system, composed by one or more interconnected bodies, like a firearm, expels some of its mass with a given velocity, (in our case the bullet and propellant gases), it will start moving in the opposite direction with a velocity that only depends on the mass of the system, the expelled mass, and the velocity at which it is thrown.
In particular, the linear momentum of the system will be exactly the same as that of the bullet and propellant gases, and the center of mass of the system will keep moving at that same velocity until an external force acts upon it.
So now I have my complex system, or firearm, going backwards, and let's say for simplicity that it is free floating in space. If I now move a counterweight inside the firearm, towards the back, I could actually get the rest of the firearm to stop moving at all... but not for very long!
If I want my firearm to remain in one piece, the counterweight will reach an endstop at some point, and transfer back the momentum to the rest of the firearm, bringing us to the starting point.
In fact, with this trick I didn't even change the velocity of the center of mass at all! What I did is simply create an unbalance, or oscillation, of the system.
But if all of this is true, then what's the purpose of the AK 107 and similar systems? In automatic firearms, a raciprocating mass is already present, the bolt carrier group, so I already have a source of oscillation. I can use my counterweight to cancel out the oscillations at all. This is very helpful for full auto firing, but is not eliminating recoil, just the shaking due to the reciprocating mass! And in fact, in the AK 107 the counterweight is thrown forward instead of backward, to counteract the effect of the bolt carrier that is going backwards.
So is there something that can be done to actually reduce recoil momentum? Yes, but at a cost: for every momentum you throw forward, you've got to throw the same behind. So either you throw less mass forward, or you throw some backwards. A muzzle brake easily accomplishes the first task: it strips the exhaust gases and throws them perpendicular to the barrel, eliminating their contribution to recoil momentum. I can do even better: I can design the muzzle brake to throw the gases backwards, and actively counteract the recoil, but to an extent: The mass of the gas is usually insufficient to compensate all of the recoil. So if I want to reduce recoil even more, I have to increase the charge, and vent a large part of it backward. I have just made a RECOILLESS gun.
So in conclusion, once you have fit the best possible muzzlebrake, there is nothing else you can do to reduce recoil momentum, you can only increase the time over which it is transferred to the shooter, to make it less annoying.
Regarding the tracers, in the video I meant flame tracers, the ones that are commnoly used. The smoke tracers based on phosphorus were in fact built in a controlled atmosphere and specific handling was used in manufacturing, as is the case for incendiary WP weapons
And regarding the pillow silencer... I must admit that I did that mainly for the thumbnail, unfortunately that's how youtube works nowadays.
Your take on physics in general is correct... But there's a lot of complicated mechanics going on in each firearm the add to the overall recoil impulse. Since guns use springs and moving parts, the impulse after the gun goes off has multiple variables. Different timings and mechanical processes make things not so cut-and-dry as your simple High School physics equal and opposite reaction conclusion. If you study about moment of impact with energy and momentum if you change the timing and duration of the event you can't get much different results with the same original force. Yes a given ammo will always generate the same force back into the gun and shooter, but how each gun deals with that force is different. not just whether or not it has a compensator. That's why a certain AR-15 firing the same ammo will have different felt recoil then another one. So your point is very basic and overlooks all the complicated things that might actually tell you about how the guns going to recoil.
Better suppression on that pillow if used lengthwise. However, I don't think people are walking around with pillows in their pockets just on the off chance you have to assassinate someone. The idea behind the 'myth' is probably that it's a suppressor of opportunity, when you just forgot to pack the right tools as professionals often do. As long as you slow the expansion of gasses and spread it to a wider area, the report is going to be quieter and probably won't sound as much of a gunshot. Better yet, wrap that pillow around your favorite killing knife on your hitman gigs.
Tbh this isn't even a myth but something a screenwriter came up with. A lazy one at that. Academically thinking it can work. However most (proper) pistols won't even fire if the slide isn't forward all the way and you shouldn't use a pistol if you can get that close.
Also a fire hazard!!!!
I always thought of "aim" as being a result of hand-eye coordination, bad aim being poor hand-eye coordination.
The tracer one was very interesting. I had never seen how tracers work before!
Per either of the two standards of metering cans, you can get something along the line of 25-30 for any standard size centerfire rifle can. The pillow thing works if the question is “does it make it quieter?” But not necessarily “do they work as well as suppressors?” Or “do they silence the gun?” And thank you for pointing out how loud 95 decibels still is.
Ok the second one is definitely just semantics.
People don't use pillows to silence the shot. The pillow is placed over the head to reduce the amount of back-splatter the shooter walks away with.
I think there’s 2 reasons for using a pillow to shoot someone in the movies, it makes it a bit quieter, yeah still loud, but imagine in a hotel, it could stop it traveling to other rooms as noticeably, but I think the other reason is because the shooter won’t get any blood splash back on them! I’ve also seen it done in the films with a silenced pistol so it probably wouldn’t be that loud from a silenced gun through a pillow?
Anyway cool vid 👍🏻
That is a very good theory
That would do nothing as far as slowing down a bullet. If there is any difference in the math, it is minimal at best..... unless the pillow was more than a foot think of dense material. So realistically speaking, a foam pillow would little effect on slowing a bullet since the super hot gases in front of the bullet would melt the foam. If it was down feathers, maybe that would change things. However, its all in the math. You might have something on the blood splatter though. Lat time I did that without the pillow, it got on everything. I was forever cleaning brain matter out of crevasses and pockets.....
Yeah, the main movie I remember seeing this done is The Good, The Bad, and The Ugly, where The Bad moved a pillow over someone's face before shooting him a couple times. I don't even think he put the barrel up to the pillow.
It might also be used for some characterization, too. The Bad seemed cold and uncaring when he put the pillow over that guy's face, like he didn't even care enough to look into the eyes of the person he was about to kill; but I can also see it being used to show someone's cowardice or lack of resolve, not wanting to see the person they're about to end.
@@rherman9085 I think that he meant the SOUND would be less likely to travel to other rooms, as it would be muffled twice, once by the pillow, and then by the walls.
A well-made wall between two hotel rooms sits around 54 dB of noise reduction. So you'd still hear a 94 dB shot, but actually a 40 dB noise passing is not that much (whether it goes unnoticed or not is mainly due to other noises covering it). I was actually surprised by the 10 dB reduction, that's a lot! But the main reason it would be useful are the splatters; a silencer fares quite better than that. Or, to be super silent, you could use just the pillow...
I destroyed one of my father's two Hi-Standard .22 mag over-under two-shot Derringer pistols dry firing it only a few times during a cleaning session...oof...I'll always read up on which firearms can and cannot be safely dry-fired henceforth...
Most people that handle guns understand that rimfires cannot be dry
He probably needs the hammer you really can't drop the hammer on empty unless it's not a hammer and it's a firing pin there is internal hammers exposed hammers
that gun name is a mouthful
@@dwsperspectiveonreality.659 Really? I've been doing it for 40 years. As long as it's a quality made rifle or pistol it's fine. Even a 1935 sears 22 rifle I can do that and it's fine. Right after cleaning that's the last step before I put it away. I've shot many bricks through that rifle.
@@robertthomas5906 it depends on the gun. I've never had a problem either, but I've had a friend break a .22 firing pin like that.
The pillow thing is to prevent entry wound blood splatter from getting on the shooter. ( assuming close contact with a pistol, not a rifle) more so than for silencing the shot.
I had low expectations because you chose the pillow fact for the thumbnail but this was actually intresting and I learned something
whoops... im dry firing my airgun for 10 years everytime after shooting xD
It's ok to do with PCP and single/multi-stroke pneumatics. I don't know why you would even cock a spring gun without a pellet.
I feel like if people don't inherently know things like this, they have no business handling a weapon in the first place...
The pillow works like a traditional suppressor in that it provides a semi closed system where the gasses can expand slower and less violently prior to being vented into the surrounding atmosphere.
I imagine you picked the D eagle as it’s semi automatic and isn’t going to bleed sound out between the cylinder and barrel
''Its not aim, its the fact you cant keep your hand in the same position''
also known as aim...?
I love how you remained "tuned" on English when you were dismantling the spring of the air rifle.
I would have expected a word with a couple of "z" instead of the "f" word
Underrated channel, deserves more exposure. Your Kentucky Ballistics video sure created som positive buzz for you.
I have a Ruger 10/22, and I always dry fire when I am out of ammo. Wish it locked back on the last round.
I know that this only Applies to few Situations, but for around here many just load a snapcap as the Last round because they are afraid of firing pin breakage.
the ruger 1022 has a system that allows for safe dry firing, unlike other rimfires, otherwise that would be a serious design flaw.
The decibel reduction is actually impressive. People don’t realize that dB’s are a logarithmic scale so the difference in 5-10 dBs is super substantial to the human ear
90 db is similar in sound to a subway train passing by right next to your ear
@@andreas6002 ok?
@@Morningstar_Actual it won't have that high of an impact on people being able to hear it
@@andreas6002 I don’t think you’re familiar first hand with subway cars and/or firearms. A subway car going by is substantially quieter than a gunshot when compared apple to apples (I.e. the noise in the subway will carry on substantially longer in duration when compared to a singular gun shot).
@@Morningstar_Actual i get that but look it is not going to have a high impact on the sound of a small explosive, people will still be able to hear it clearly from very far away
Revolvers or well, most of them that don't use a particular system (unlike the nagant) have gaps where the gasses quit, not only something that may render the gun unsuppressable, but also dangerous if your hand is next to/over the cylinder's end
*laughs in constant recoil*
Then again, felt recoil and recoil energy is two different things.
Wow, this is actually a very logical, knowledgeable video that even provided me with a couple of very useful facts! Thank you!
I thought people in movies shot their target through a pillow to stop blood from getting on them
(Paraphrased) "Adding a muzzle brake will reduce recoil, and also adds weigh which doesn't reduce recoil, but does reduce the perceived recoil."
On High School Rifle Team (Yes, I'm that old), my favorite was one named "Big Bertha."
She was the heaviest lady we had, at 23 pounds. And a .22 caliber bolt action.
In movies, the pillow is used to stop the blood splatter. The sound design team generally thinks otherwise.
Blood splatter mainly occurs at the exit wound (if there is one) which is on the opposite side, but I guess a large pillow would still help shield from any backsplash . Wrapping the whole target head in multiple layers of duvet would probably work better.
Something salient about the pillow "silencer", and silencers in general: Silencers in general don't silence the shot like you see in movies, they just make it quieter. The dB scale is logarithmic, so while you measured a 10dB reduction in noise, that is actually 3.3x quieter.
@@lapin46 I would imagine that's highly frequency dependent, but I had not considered a non-linear response.
The noise from the gun come from 2 factors: 1. The gas expanding 2. the bullet breaking the sound barrier (sonic boom). So putting a pillow might effect the first factor but not the second.
Bsa airguns recommend that you dry fire them rather than trying to de-cock the action as it can damage the cocking lever or bend the barrel.
Pre-charged air guns are fine to dry fire but also fine to decock by holding the bolt back and letting it go forward slowly like Dr-cocking a firearm hammer.
The pillow silencer was done when criminals used 38 specials, a weak gun by modern standards but they used hollow point bullets way less than we do now, and solid bullets have better penetration. The frequency of sound determines whether it goes through walls, so to test this properly you need to measure the sound from another room. At the time that myth was popular, people usually had a Radio on fairly loud in their house. People nowadays have a TV on a lot of the time, so you will have to find out the average volume of a TV to get an idea of how well this could work in a real-world scenario. Also, the closest person in the building could have several walls between him and the gunshot, and a pillow could easily make up the difference between hearing and not hearing it.
I've sheared off tips of firing pins before from dry firing centerfire weapons. "ultracompact" 380/9mm pistols seem to be the most susceptible to this.
Fun fact while pillows really only dampen the gunshot, it does in fact stop blood splatter from hitting you at close range.
While also preventing you from seeing their face which makes it a little easier to pull the trigger.
That and you won’t have to see the back of their head popping open like a ripe watermelon.
I’m gonna guess you chose the deagle cause it’s a one shot headshot in MW 😎
😉👍
Cod sucks the deagle has been a one shot headshot in counterstrike since 1999
any gun can technically be a one-shot headshot.
While Recoil may not be diminished, Muzzle Flip can be reduced with the proper parts. The 'Glock Store' sells Tungsten guide rods for Glock handguns which substantially reduces felt recoil and muzzle flip. Mine works GREAT !
recoil energy can't be reduced but the feel can thats what he said
Imagine if pillows worked better than real suppressors and the government had to regulate them
The manual for my Beretta Bobcat .32 specifically says not to dry fire it. My Sig Sauer P226 manual makes no mention of it.
You picked the desert eagle because when the round is fired there is only one way for the gas to escape, but with a revolver the gas escapes out the cylinder
Tracers can still 100% light stuff on fire. It happens at the army range all the time.
That's definitely true. Some ranges prohibit their use because they set the targets on fire
Recoil CAN be mitigated. There is HOW LONG it takes the force to act on you. If you are using a single-shot, then you get the FULL recoil impulse at once. If you use some sort of semi-automatic, then some of the force will go towards moving the bolt back, which will spread out the recoil in time, as the spring begins to take up pressure. This can make the shot more comfortable.
>lower discomfort
That is the point of lowering recoil, it makes it easier to handle the recoil, drawing it out instead of making it a single quick pulse, and makes it more controllable. They don't reduce recoil, but they make it more bearable, and in turn you get a very similar effect like a muzzle break, when combined it can make a very distinct difference in shooting the gun.
you can't lower recoil it is physicaly impossible but you can lower the recoil you feel
@@andreas6002 that's what I'm saying here
@@glitchyglitch1235 oh sorry i read your comment wrong
Main reason for using the pillow is to keep the blood and bone off of you not to quiet the shot
Some Centerfire guns can be damaged by dry firing but the main reason that would happen is if it's an old gun that may with a more fragile firing pin
Let's face it though... the pillow thing was always more about containing the blast and preventing the target's insides from splashing back on the shooter. Keeps things tidy.
05:44 now that's a beautiful gun!!
I'm guessing you chose the deagle because if you used most other pistols with the same cartridge (which are mostly revolvers) a lot of the gases would go out the sides of the cylinder gap. But with the deagle, all the gas goes out the barrel and it would have more of a possibility to have the pillow suppress more of the gases and therefore more of the noise.
Exactly! good job!
The pillow myth is still a myth because it's usually shown to drop the sound down to a whisper. The truth, as you have demonstrated, is that the sound of the gun is reduced somewhat. But the gun is still pretty loud. The same situation with suppressors. They work, to some degree, but nothing like what is shown in the movies.
many people I talked with about the pillow silencer myth say the pillow is actually meant to reduce blood spatter.
The CZ52's firing pin is pretty fragile,it breaks if it's dry fired too much I heard.
The CZ52 is a remarkably underdesigned pistol, nothing like the much better CZ82 or CZ75.
@@0neDoomedSpaceMarine Too bad,such a cool design,at least from my perspective.
Well done! BTW, subscribers, this is the second gun channel I’ve come across this morning where the notifications were turned off. Must have happened in some update? I’ll be going through all my channels this weekend to see which ones got shut off. Remember: UA-cam is not your friend.
A pillow would also help with blood spatter at close range. In John Wick there is a scene of the character Perkins holding a pillow over someone's face then uses a revolver. She uses a pillow to avoid the spray.
Great video... loved when you were taking the air gun apart... been there many times lol
The way you have the pillow folded over, I wonder whether having the gun stuck in the middle of the pillow fold would make it quieter because there's pillow material all around it.
A CZ52 pistol, which is chambered in 7.62x25, should never be dry fired. The pistol has a cast firing pin and is easy broken with one or two dry fires. The automatic pistol does have a decocker though and hardened machined aftermarket firing pins are available which are safe to dry fire.
Pillows do work very well at suppressing noise from long guns, as long as they are not semi-auto or revolving cylinder. A .22 rifle is quieted to almost nothing (quieter than a pellet gun) from being fired with the muzzle held firmly against a soft target. I tested this with bolt action, pump, lever action, and semi-auto long guns, and a revolver handgun. I assume the revolver would act the same way in a long gun configuration, it's not significantly quieted, and the semi-auto is much quieter, but not as much as the pump, lever, and bolt guns. Haven't tried break action, but they should be just as quiet as manual action repeating rifles, even in pistol configuration.
however recoil's effect depend greatly on the design, which is why the fugly chiappa rhino is great to shoot
Muzzleloading revolvers if properly adjusted can be dry fired because the hammer should not touch the nipples if no cap is installed. If you don't adjust them like just about everyone does, you end up ruining the nipples and having problems when removing the spent caps. You also get better precission if the hammer does not touch the nipple because the end of travel is much softer with the copper absorbing some of the force
I always thought the pillow thing was just to stop blood and grey matter splashing all over you when performing a point blank execution.
but what would it sound like shooting though a pillow and another head substitute, to then go though a mattress?
I have to wonder if a different type of pillow, such as a down pillow, would have a significant effect on the sound of the weapon firing. I'd have tried a few different pillows, see which dampens the noise the most.
Shooting through a pillow is not to muffle the sound but to stop the back splatter of blood, bone and brains. A blanket or jacket works just as well. Or so I've been told :)
I have seen this type of thing in action. If there is a larger target against it, like the ground, or I guess a living thing, it significantly reduces the noise. Much more so if it is a locked breech firearm such as a bolt action. I know from shooting trapped animals at contact distance with a .22, it can even be quieter than a suppressor.
One of the folks at my long range shooting club insists on putting a snapcap into his Remington 700 rifles. His reason being that if you dry fire the firing pin edges that retains it inside the bolt will experience too much force if there is nothing for the firening pin to slow it down. But in my opinion it's pointless since the pin is made out of pretty strong material that can withstand hitting primers all the time
The pillow is used to avoid back splatter towards the gun.
nice. i wonder what it would do with subsonic ammo?
Some hammer fire pistols can have part breakages due to dry firing, typically the part breaking being the firing pin retaining pin. Not a catastrophic failure, or dangerous, but annoying, and deactivating.
the shop owner dry firing a cross bow makes me feel more confident about my future hopes of being a gun store owner lol
This person knows nothing about how to suppress a fire arm. You have to rap the pillow over the gun, or put the gun inside the pillow.
Not something that most people will have to worry about, but dry firing crew-serve weapons (M249, M240B, M2, etc.) can damage the bolt carrier over time. You can still technically dry fire it, however you shouldn't let the bolt ride forward on it's own, instead just ride the charging handle forward so the bolt doesn't slam.
About myth 5. Some centerfire rifles, especially Mauser style rifles, have a lot of vibration transmitted through the firing pin. This can lead to fracturing, I have seen like new and functional firing pins have the tip break with a few dry fires without the firing pin show external damage. Just something interesting I found, maybe a disclaimer to throw in the video
Not just centerfire rifles. Some older shotguns can also break the firing pin tip from dry firing- and single action revolvers with fixed firing pins on the hammer like the one demonstrated in the video. It usually takes a lot of dry firing to break anything, though. What happens is that the tip of the firing pin comes in tension against inertia when the pin or hammer is stopped hard against steel. Thin, small things like firing pin tips are a bit tricky to heat treat correctly, so especially in older guns the firing pin tip has a tendency to be brittle and prone to developing material fatigue. What holds up fine in compression in normal firing may break when dry fired and it gets under tension instead.
I saw someone ignite a 7.62 Nato tracer bullet by moving the protective cover over the tracer material, so you can ignite them by exposing to air. This guy had the burn on his fingers to prove it.
I knew tracers were like small road flares because I pulled a .50 BMG tracer and lit it after I removed the thin copper(?) disc at the base of the bullet. When lit it with C-ration matches I burned my fingers. Road flares burn at nearly 3,000 degrees F, and the tracer may have been that hot too for a couple of seconds. All I know for sure is that it was painful and discolored my burning skin, but not as bad as a fireworks accident years later.
The pillow is used purely as a preventative measure, to stop blood and brains splashing on the executioner, as already pointed out in a previous comment.
Sealed chamber is why you chose the Desert Eagle. Where you would normally have a cylinder gap, from which you you would have a higher sound signature of gas expanding across the gap.
Correct 😉👍
The CZ 52 pistol in 7.62×25mm has a brittle firing pin and it will break if the gun is dry fired. I was hit in the face by the rear end of the firing pin of a CZ 52 that had broken. The broken firing pin was propelled backwards by the recoiling slide. Fortunately, I was not injured.
The pillow halves the volume, which is cool, but it's still about twice as loud as a motorcycle
The reason someone uses a pillow is not to silence the round it is to prevent blood blowing back on the shooter surely. No point in messing up a good suit unnecessarily is there.
I've heard that older revolvers that have a swinging firing pin mounted on the hammer can also break if dry fired too much. I don't know how true that is, I just try to always have snap caps in my guns if I'm dry firing them.
Hence the reason why tracers are normally loaded every 3rd to 5th rd.
maybe different kinds of pillow stuffing have different effects? like foam, cotton, wool, feathers? movies seem to favor pillows with feather or cotton filling.
Dry firing, I have always understood, that anything with a “firing pin” dry fired causes excessive vibrations in the pin, which can cause cracks in the pin.
Desert Eagle: the ONLY Garand-style, fully gas-locked pistol commonly available
The pumpkin looks freakout 🤪🤪🤪
I guess why😂😂
dry firing will damage centerfire guns or rather break the firing pin spring if the spring is old.
i always thought they were trying to stop the blood from getting on them not using the pillow as a silencer.
You can damage some center firing guns by dry firing. Modern Military, Police or self defence guns are pretty much immune that is true. But particulary with older hunting guns it is possible to loose the tip of the firing pin when dry firing. The firing pin tips are very hard and the shock from hitting the end stop is often enough to just snap the tip clean off the rest of the firing pin. Generally these guns are not designed to be dry fired and even deformation of some parts of the firing pin can occur getting it stuck in the firing pin channel.
its more about the spring on old guns these days. stretching the spring can break it if the spring is old.
Dry firing a Auto 5, or an equivalent like Luigi Franchi ARC, or Verney Carron ARC (who they are centerfire gun btw) will quickly damage and break the firing pin
Pillows are actually used to avoid an assassin getting spattered with his victims blood in point blank shots to the head, thus getting tagged with incriminating forensic material.
It does leave burn marks from the shot to the pillow, but the first event is more highly avoidable.
There are more readily available and more efficient ways to moderate the sound of gunfire, (silencers), since the decision to kill an individual has been already taken.
you can do the same with a .22.
10 decibels is significant. Every 3 decibles doubles sound energy, and 10 decibles doubles sound perception
90 db is similar in sound to a subway passing by im pretty sure it would not help at all www.uofmhealth.org/health-library/tf4173
I once fired a felt cleaning wad only through my 15 joule spring air rifle, at a thick piece of wrought iron (an excavator bucket tooth tip) and it made a supersonic crack, vanished in a mist of white, and left a dent in the steel. The gun was very unhappy and the spring was badly warped 😕
Give yourself a high friction grip on the pistols by wrapping your support hand around your strong hand so that your support hand knuckles (from the inside) are parallel with your strong hand knuckles. Practice that for an hour a day, everyday. Your thumb should be aligned with your index finger as they both lay along the receiver snd you should feel a slight strain in your forearm running from your support hand thumb and back. You'll get use to it, its just a bit of stretching and it doesnt have any negative affects.
10 decibels of noise reduction is quite a lot in reality.
Going back to the recoil impulse, the major part of recoil on a semi-automatic firearm is the reciprocating bolt or slide. The Recoil of actually firing the projectile is minimal.
man 90 db is so loud it would still be heard even if you were at a long distance
Retest the pillow one - because here the test is conducted as though the target, Mr Pumpkin, isn't in a bed, you're just using the pillow as a supressor. The myth as used in tv and film is generally where the target, here, Mr Pumpkin, is lying in a bed and so the trajectory of the round(s) fired through the pillow aren't going to exit the target's head into open air, but also go through the bedding. So perhaps retest, with Mr Pumpkin lying in a bed, his head on a pillow, and you use a second pillow as the supressor?
:D
I can't even use a pillow to block out moderate noise coming from another room.
Can bolt actions be dry fired without damaging it?
If its center-fired and made in the last 80 years, probably.
Should have tried a .22 and a pillow
Thanks for the vid; I actually learned a few things! However, I'm don't agree that dry firing compressed spring air rifles will always damage them. I've had a .177 break-barrel air rifle since 1974 and have dry fired it many, many times and the rifle still shoots perfectly well. Mine is a single cock type; that is, you open the barrel and cock the spring by pulling the barrel down once. It is not a pump type where you can pump it more than once though. I'm sure you're correct and that many air rifles would be damaged but I'm just saying "not all of them". Perhaps you can investigate and do a video on why it's not a problem for some?
Great video. I do have some observations.
1) Dry firing causes slight overtravel of firing pin that would ordinarily be limited and cushioned by the the softer primer cup when round is present. Peening of firing pin in channel or cratering around firing pin opening on frame, especially of lower quality metals occasionally occurs.
2) When discussing suppressors, you used self loading pistols. I would be curious if you'd use a single shot pistol like a Thompson-Center, pushing tightly against pillow and pumpkin, essentially forcing gasses into pumpkin for cooling and dissipation. What kind of reduction would you get?
3) You've mentioned doing something on strange munitions, on another video. How about examination and commentary on the Soviet PSS pistol, with cartridge that contains all the blast gases, none dissipating to atmosphere. The Russian language videos demonstrating these seem like only sound is mechanism.
Will be looking forward to your next video.
Most modern centerfires can be dry fired but avoid it with old ones. The metallurgy was not a precisely controlled and the firing pin might not be hardened perfectly. The shock of a dry fire could break it which leads to the second reason: getting replacement parts. It's not a big deal if replacements are readily available but those from decades ago whose manufacturers are out of business might be a big problem. You could turn your classic into a paperweight.
its more to due with the spring attached to the pin
