Your ability to apply folksy hands on personal experience/interest regarding firearms with deliberate scientific set up and analysis of your experiments is what keeps me coming back to your channel. Keep up the good work.
I love these types of videos. Various bullet weights with same velocity, or various velocities with same bullet weights. I wonder how they would compare with the same bullet weights, but fired from a 30-06, having the higher velocities.
I thought you did a SPLENDID job of pacing and keeping the flow very engaging. I've had similar classes on penetration and types of penetrators when preparing to deploy. They could have used this video and then broken it out into five 30 minute sub-segments on each principle. They'd have saved loads of time and and done a better job. You've done and amazing job with the subject.
I did a similar test with my 375 ruger. At 50 yards, my 300 grain solid cut cleanly through a 1/2 inch cold rolled steel plate and continued through 2 gallons of water (exploded the first gallon and pierced and lodged in the back wall of the second jug). Excellant video!
This channel is just the right kind for me. It satisfies fully all my curiosities about firearms science. I wish there are more gun channels that mess around with guns rather than showcase new and cool guns.
Very awesome and informative video. I love how your channel goes very in-depth with everything in regards to firearms and ballistics. I'm very surprised that your channel isn't more popular; you deserve it!
I just discovered your channel. I've been binge watching your videos. There's lots of gun channels for history and mechanics, but not so many for nerdy experiments and explanations (Except InRange).
It's quite incredible how common and cheap (still to this day!) Soviet/Chinese/Warsaw Pact surplus rifle ammo is. Given how all of them do have some sort of a steel core to their projectiles, it's no surprise to see them scattered all around the range on a busy sunday.
Most are un-hardnened steel penetrators so their actual performance is limited. Some are hardened steel and the penetration from those bullets is very good.
Excellent video, i have had this discussion many times with people who don't understand the physics, faster projectiles penetrate deeper when talking about non armour piercing ammo. Speed defeats body armor ! thats why the 5.7X28 can penetrate some body armor that is rated for pistols.
I did a similar experiment with an SKS and Chinese 7.62 X 39 steel cased, steel core ammo. My targets were 5/8" 1020 HRS and 3/4" 1020 HRS. I shot 5 rounds at each target at 30 yards. The Chinese ammo fully penetrated the 5/8 steel, leaving a 1/2 inch hole through. The 3/4" plate had a crater about 5/8" deep with a substantial bulge on the back.
First time here, TU! You really pay attention to detail. I like how your video focuses on the details & not the fluff. I look forward to some of your other videos.
30 years ago I was shooting at falling plates with 7.62. The cops had been shooting them with Ruger 5.56. That had put holes in the plates, much to the annoyance of the range warden.
can't believe this channel doesn't have 1 million subscribers. great video ideas, scientifically tested and explained expertly. keep up the great work and you'll be popular in no time!
AP will probably give an extra inch of pen. yes to the BMG going deeper, assuming it has better sectional density or higher velocity. but if it has the same sectional density and velocity of the .308 then the depth should be the same; with a wider crater. my guess
Do be careful with AP bullets. When they impact, the jacket ("sabot") will be thrown back towards the shooter. I suffered a minor wound to an arm from a 30-06 AP jacket thrown back at me. Didn't go very deep, but if it had struck my eye, it could have been catastrophic. Good video, by the way.
Typically (and it seems it is the case here) the hollow point designation on rifle ammunition just points to the method of manufacture. Some bullets have closed tips and open backs, some have closed backs and the tip is left open when it is squished into a point. There different types of manufacture have an effect on ballistic coefficients as well as weight distribution when comparing the mass in the front and back of the bullet. For expansion, soft points are traditionally the focus of rifle ammunition. You can find videos with hollow point bullets such as these being shot at different mediums and showing little to no deformation and no expansion. Soft points on the other hand can expand pretty dramatically.
What you said about HPBT is definitely correct, butthe hollowpoint I used was a monolithic design, it has no jacket and core, and is just one single piece, being designed to expand in soft targets. Actually they do it pretty well. It was a barnes TSX
@@Backyard.Ballistics the most interesting things start to happen when you shoot the hardened armour grade steel with different bullets and you approach and later exceed 1500 meters per second!I managed to get to as much as 2500 at some of my experiments using (semi-)conventional propellants in a round more similar to German hyper velocity 7,92×94 anti-tank rifle rounds and out of a custom barrel that could withstand significantly elevated pressures!So it turns out that when approaching these speeds at up to 1200 meters per second FMJ doesn't leave a scratch at all on an inch thick AR-550 plate while at the same speed the AP with a thermo-hardened steel core(btw 10.8 grams AP and 13.2 grams FMJ from regular 7.92×57 Mauser in my case)-goes through the entire plate! Although when you get to about 1500 meters per second for both-if you introduce the same second plate behind the first one-the results will be that first of all this time they both will make it through, but leave the entirely different holes and different damage will be seen on the other plate! So the AP will not leave the hole too much different from what it left at 1200 and on the second plate you will see either one or 2-3 substantial indentations that will be left by the hardened steel core that will usually break in 2-3 pieces while going through the first plate.Meanwhile the hole made by FMJ will be vastly different:it will be not squeezed aside kind of thing like that in case of AP-it will have mostly fracture-type deformation and cracked edges; the bullet just breaks and crumbles the metal it hits at this point! And on the other plate you will have a number of small hit marks left by pieces of the first plate that will be up to 2-3mm deep.. AP still will leave more damage and at least deeper scratches on the second plate.At even higher velocities you will eventually get some of the AP bullets cores making it through the second one as well although rarely and only starting close to the maximum of 2500 m/s while FMJ-s will not go faster than 2000-2100 without modification! So you can use solid copper or brass after that.. Besides the propellant that I used was granulated PETN (pentaerythritol tetranitrate) from pure to get maximum velocity and at the lower range of speeds I mixed it with regular gunpowder!
An AP round would probably just penetrate a piece of mild plate that size if it is loose like that. A .50 probably knock it straight down the road. A really light round traveling really fast will penetrate almost anything. Your detail is astounding..
Yeah I wish at the point he had us all pause to answer he would tell us more like relevance if sectional density. I think showing the difference between a 220 grain round nose and a 147 FMJ would be interesting. Also what’s the metallurgy of the steel plate???
You used a .416 Barrett instead of an actual .50BMG bullet and found that the bullet created a large crater and the metal bulged heavily... It was my understanding that all .50BMG ball ammo was steel core already and the behavior of the .416 Barrett bullet suggested that it was not steel core.
Just subscribed. Love your channel and explainations. Speed is king, there is a video of a sabot 55 gr .223 bullet not steel core. Going thru a 1/2 AR500 plate. But it was going just over 5,000fps.
The FMJ rounds you fire are standard military ball. Not designed for steel but for flesh and light or non light armored vehicles 17-22 gage steel. There are armor piercing rounds for that cal.. A good comparison test non the less.
since we got told back in the day the slr would push a 7.62 nato projectile at about 823 mps id say the german ones were probably inconsistent duds that got rejected but the italian ones were about spec
You will improve on the plate penetration by bolting it to a heavy frame. The mass of the plate seems to light to hold it in place. This effect is a function of bullet velocity. The slower the bullet, the more is pushes the plate away, rather than penetrating it.
THE 308 HOLLOW POINT IS NOT A HOLLOW POINT! IT IS KNOWN AS OPEN TIP BULLET RUSSIAN TECHNOLOGY ( ALSO DONE IN AK M43 ROUND 7.62 X 39)WHEN AN OPEN TIP BULLET IS FIRED A BUBBLE OF AIR FORMS AT THE OPEN TIP SO DIVIDING THE RESISTING AIR THUS IMPROVING ACCURACY YOUR CHANNEL IS AWESOME SIR!
3:05 - A copper-plated hole. I had high hopes for that solid copper bullet (did you say Barnes?...I'll have to go back and look). Please consider some other testing for that particular bullet - regardless of caliber. As usual, thanks for furthering my education.
Ahhh the old L1A1 SLR…….. what a wonderful weapon, cradled a few of them in my arms in my time, no sling and running for miles, those were the days….. I bet I could still field strip one blind folded in less than 15 seconds…. Take about two minutes two put it back together though!!!😂😂😂
U should redo the test. And then test the legend of how early AP ammo attempts was with reversing the bullet backwards and then firing them vs metal tanks in war. It's said they had good results at one point
with similar masses and similar velocities, they are going to dump very similar amounts of energy to the point of impact ablating the material. and as kinetic energy is measured as MV^2 the velocity makes more of a difference, velocity will ablate more material giving you a deeper hole., having a longer bullet with the same mass would also deepen the hole, it would be a thinner hole but it would ablate a deeper hole. this is how anti tank weapons work. shaped charges deliver heat and kinetic energy to heat up and ablate the material over a very small area tunnelling through, whereas long rod sabot rounds exchange surface area for length, so it can spend more time ablating the material giving a smaller but deeper hole.
6:42 .308 AP should clear 3/4" mild steel. Regular .50 BMG should clear the same steel plate; if you attach it to something heavy. Else, the small plate may just be thrown a long way, unloading the bullet to plate interface, reducing penetration.
I loved the video! Have you considered casting and using like titanium projectiles? Because that might be interesting, if it doesnt mess up rifiling Actually why not try old black powder .50 cal ball rounds? Just to see if they do anything unusual Just ideas Love the vids!
Jayk Puten I’m not sure titanium would make a good projectile as it would be too hard for the rifling to grip it but maybe a titanium cored bullet being very light could get you a higher muzzle velocity?
@@ArchieKeen1 yeah thats why my first thought was it messing up the rifiling... But what about a titanium barrel? I juat wonder if that would go through armor plating better Or a heavier bullet like depleted uranium (arent tanks using that as armor?) or something
Thank you for suggesting, it's always useful for me. Regarding titanium, it is not very suitable for making bullets, because of its low density (4.5 against 7.8 Kg/liter for steel), which is instead its main advantage for the aerospace industry. That's why tungsten and depleted uranium (density around 19) are used for advanced armor piercing designs (not in portable weapons, by the way, where special steels are almost exclusively used)
@@Backyard.Ballistics That kind of sectional density could lend itself well to a modernized take on the 7.92mm CETME, a little denser than the aluminum originally used but ballistics advances since the 50's should more than compensate for the denser material.
Interesting test, but I'd like to see it done again with the steel plates anchored down. When the steel plated get hit they fly off with tremendous energy. This is all wasted energy that otherwise would have been directed into the bullet penetrating the steel.
@6:40 I'm guessing the .50 BMG goes right through regardless of the bullet, and a .308 (which is almost identical to 7.62 NATO except rated to maybe 5% higher chamber pressure, right?) with an AP bullet will probably still not be enough to get all the way through that quantity of steel.
Huh. I'm surprised the .50 was stopped! It looks like it is causing more structural deformation that would weaken the plate across a wider area than the AP .308. Do the impacts change any of the steel's physical properties, maybe making it more brittle where it's been deformed? Would it be possible for you to test secondary shots (either the same rounds or even smaller calibers) in the vicinity of an initial impact? A second .50 BMG within a couple inches of the first one would probably punch through.
It's very interesting how the impact of the .416 Barret (50BMG stand-in) appears to have 'work hardened' the material at bottom of the impact crater. Would a second impact from a .308 in the same location be more or less likely to penetrate any deeper into the steel? What about the effect of repetitive impacts of the same type bullet on the same impact location? I would enjoy watching such an experiment and its results.
This is a very clever question, which I recently had to answer for a project I am working on. The simulations show no significant depth of crater difference for subsequent hits on 4130 steel (johnson-cook model). The work hardening appears to be very localized, and compensated by residual compressive stresses. I will etch my specimens and show the results in a following video, hoping to highlight stresses and work hardening.
My Fal will Penetrate an standard 12" I beam with 7.62 NATO green tip, just watch out for steel splinters blowing back if you start shooting steel with steel my friend.
.308 AP? That should punch through. .50 BMG? Unsure. Never fired one. I'd assume it would fully penetrate, but I don't have enough info to make that call.
Ciao, noto che sei italiano e mi chiedo, dato che qui non è permesso ai civili il posesso di munizioni AP, come hai fatto a sparare con il penetrante? Tra l'altro quello se non sbaglio è tungsteno, quindi dovrebbe essere una M993. Grazie mille in anticipo.
Great to see another video from you. Big fan here in California. I have a question regarding the shooting ranges you have in Italy, do you guys have the really nice fancy shootings clubs like they do in Switzerland, German, or Austria (things like electronic targets, 300m indoor, restaurants, etc.)? Or are Italian gun ranges more like how most are here in the U.S. in that they are pretty basic. Thanks in advance.
We have both "Istitutional" and private shooting ranges. So, based on the money flow and the numbers of associated, they could have more or less features. Some have eletronic targets, many have 300m ( some completely indoor in old caves, I heard, but every single one has a roof over their head). Usually no restaurants, but often a bar is included. There's no a common ground, except for the safety measures.
Diego replied before me, and I totally agree. I would just add that one main difference with the US is that we have high population density, so we almost never have the chance of letting bullet fly out of the range without a backstop, so our ranges tend to be more "closed" than some of yours
@@Backyard.Ballistics Most areas in the US that are extreme range (1000 yard +) are usually either Federal Government land (we call it BLM or the Bureau of Land Management), or they're a large private range. You'll have a few places that have 1000 yard ranges but it's still kind of rare. There is a long distance range next to me in Los Angeles but it is about 80km away and it takes me well over 2 hours in traffic just to get there. But I think the big thing I've seen is the quality of our shooting ranges out here are much lower than yours. Even in states that are gun friendly, it's rare to see things like e-targets or modern upscale facilities, and the largest indoor range ranges you'll find in the entire country are generally less than 100 meters...also w/o e-targets. I just think it's a shame that we have this amazing ability to practice this skill but the facilities are sub-standard when compared to countries that are much more restrictive.
@@Furiereindulgente Thanks! It's nice that some places have places seem to put some money into their facilities. I was doing a google search, and I see there are a lot of "Tiro a Segno Nazionale" locations, Is that strictly for members of Olympic disciplines or are they open to the general public?
@@edweiser63 the "Tiro a Segno Nazionale" are the institutional ones, open to the public. They can have ranges for air guns, for olimpic .22lr, for pistols or for long range rifles. Then you can have other institutionals just for skeet shooting, but all of them are for the general public, olimpic athlets have to share it!
I saw a video saying that in WW1 germans seeing tanks for the 1st time took apart the mauser bullets and reinserted the bullet backwards. This was apparently more effective. I think your video makes it clear that turning around the bullet wouldnt matter since all of the energy is dumped in the plate so bullet type and shape is irrelevant. What do you think of this?
@@Backyard.Ballistics The presenter was telling it as fact and that it was effective. I think the effect would be as you have shown. All of the energy is being transferred. Without a hard core the shape of the bullet is irrelevant. It could be an propaganda of germany... makes it sound like they had something effective when they really didn't... good for moral while they worked on something else. Like most of these silly ideas if they were so effective then why go through the expense of developing special bullets when the soldiers just need to flip a few projectiles and take out a tank. If anything I would think a pointed bullet may help with the transfer assuming it doesn't glance off. It will create a small initial dimple which will allow the rest of the bullet material to collect in and expand.
Was that a hollow point or a match round? Cause most of the match rounds I purchase have that tiny hole on the tip compared to the relatively larger holes with ballistic tips on the actually marketed as hollow points I have purchased.
Backyard Ballistics Yeah looking at the box it says HPBT in the description of the Sierra match king bullet. Otherwise no where else on the box does it say hollowpoint. Little weird that they wouldn’t say that elsewhere but meh.
No uranium containing ammo for portable weapons (including 50 BMG) has ever been deployed, for many reasons that go even beyond its toxicity and (slight) radioactivity. In peculiar designs requiring high density, like SLAP rounds, cemented tungsted carbide is used instead of tool steel.
I'm looking to move to a European country from America. Seems like the Italian gun laws are good, how do they compare to America. Love to see a video about it.
L1A1, ohhhhh I'm drooling over that beautiful rifle.
Agreed. One day we shall have them again!

The Chinese ammo fully penetrated the 5/8 steel, leaving a 1/2 inch hole through. The 3/4" plate had a crater about 5/8" deep with a substantial bulge on the back.

I really like your videos. Keep up the good work.
6:42 .308 AP should clear 3/4" mild steel. Regular .50 BMG should clear the same steel plate; if you attach it to something heavy. Else, the small plate may just be thrown a long way, unloading the bullet to plate interface, reducing penetration.
I forgot to mention it in the video, but the barrett and AP plates were 1 inch instead of 3/4, they would have probably cleared the 3/4
Are we all just not going to talk about that awesome thumbnail?
YES actually I LOVE Your videos, thank you so much for it, and please for more :)
The formula for the force of an object with speed is( mass x velocity^2) /2
You need mass and velocity. Something like a hardened steel penetrator is very effective but there are better options out there although exepnsive.
I loved the video!
Have you considered casting and using like titanium projectiles? Because that might be interesting, if it doesnt mess up rifiling
Actually why not try old black powder .50 cal ball rounds? Just to see if they do anything unusual
Just ideas
Love the vids!
Jayk Puten I’m not sure titanium would make a good projectile as it would be too hard for the rifling to grip it but maybe a titanium cored bullet being very light could get you a higher muzzle velocity?
@@ArchieKeen1 yeah thats why my first thought was it messing up the rifiling...
But what about a titanium barrel? I juat wonder if that would go through armor plating better
Or a heavier bullet like depleted uranium (arent tanks using that as armor?) or something
Thank you for suggesting, it's always useful for me.
Regarding titanium, it is not very suitable for making bullets, because of its low density (4.5 against 7.8 Kg/liter for steel), which is instead its main advantage for the aerospace industry. That's why tungsten and depleted uranium (density around 19) are used for advanced armor piercing designs (not in portable weapons, by the way, where special steels are almost exclusively used)
@@Backyard.Ballistics That kind of sectional density could lend itself well to a modernized take on the 7.92mm CETME, a little denser than the aluminum originally used but ballistics advances since the 50's should more than compensate for the denser material.
Good video I’m excited for the armor piercing video
Good video keep making videos I love these
Interesting test, but I'd like to see it done again with the steel plates anchored down. When the steel plated get hit they fly off with tremendous energy. This is all wasted energy that otherwise would have been directed into the bullet penetrating the steel.
Incredible content!!
Now try the 16” / 50 caliber mark 7.
@6:40 I'm guessing the .50 BMG goes right through regardless of the bullet, and a .308 (which is almost identical to 7.62 NATO except rated to maybe 5% higher chamber pressure, right?) with an AP bullet will probably still not be enough to get all the way through that quantity of steel.
Huh. I'm surprised the .50 was stopped! It looks like it is causing more structural deformation that would weaken the plate across a wider area than the AP .308. Do the impacts change any of the steel's physical properties, maybe making it more brittle where it's been deformed?
Would it be possible for you to test secondary shots (either the same rounds or even smaller calibers) in the vicinity of an initial impact? A second .50 BMG within a couple inches of the first one would probably punch through.
I imagine that the 308ap will go about as deep as the 50bmg, that being said I think they will at least make a pin hole in the back of the steel
You get better armour penetration using 5.56 believe it or not. It’s the VELOCITY that penetrates armour
Nice rifle. I've handled a couple of the wooden ones.
It's very interesting how the impact of the .416 Barret (50BMG stand-in) appears to have 'work hardened' the material at bottom of the impact crater. Would a second impact from a .308 in the same location be more or less likely to penetrate any deeper into the steel? What about the effect of repetitive impacts of the same type bullet on the same impact location? I would enjoy watching such an experiment and its results.
This is a very clever question, which I recently had to answer for a project I am working on. The simulations show no significant depth of crater difference for subsequent hits on 4130 steel (johnson-cook model). The work hardening appears to be very localized, and compensated by residual compressive stresses.
I will etch my specimens and show the results in a following video, hoping to highlight stresses and work hardening.
@@Backyard.Ballistics Thank you!
love your videos!
My Fal will Penetrate an standard 12" I beam with 7.62 NATO green tip, just watch out for steel splinters blowing back if you start shooting steel with steel my friend.
oh my gosh i hope @demolitionranch knows your videos dude, that funny texan is going to ********** over your penetration tests
.308 AP? That should punch through. .50 BMG? Unsure. Never fired one. I'd assume it would fully penetrate, but I don't have enough info to make that call.
Ciao, noto che sei italiano e mi chiedo, dato che qui non è permesso ai civili il posesso di munizioni AP, come hai fatto a sparare con il penetrante? Tra l'altro quello se non sbaglio è tungsteno, quindi dovrebbe essere una M993.
Grazie mille in anticipo.
nice FAL bro
I expect them to leave equally deep craters as the velocity is about the same.
Mass matters
Nice work....It's all about hardness and speed...Not mass..Give me a BB moving 10,000fps and I'll blow right through that plate..
Which Gun Is Better Against Steel? The most powerful one with the most solid projectile? Does this need testing? Tungsten core. Simple physics.
Great to see another video from you. Big fan here in California. I have a question regarding the shooting ranges you have in Italy, do you guys have the really nice fancy shootings clubs like they do in Switzerland, German, or Austria (things like electronic targets, 300m indoor, restaurants, etc.)? Or are Italian gun ranges more like how most are here in the U.S. in that they are pretty basic.
Thanks in advance.
We have both "Istitutional" and private shooting ranges. So, based on the money flow and the numbers of associated, they could have more or less features. Some have eletronic targets, many have 300m ( some completely indoor in old caves, I heard, but every single one has a roof over their head). Usually no restaurants, but often a bar is included. There's no a common ground, except for the safety measures.
Diego replied before me, and I totally agree. I would just add that one main difference with the US is that we have high population density, so we almost never have the chance of letting bullet fly out of the range without a backstop, so our ranges tend to be more "closed" than some of yours
@@Backyard.Ballistics Most areas in the US that are extreme range (1000 yard +) are usually either Federal Government land (we call it BLM or the Bureau of Land Management), or they're a large private range. You'll have a few places that have 1000 yard ranges but it's still kind of rare. There is a long distance range next to me in Los Angeles but it is about 80km away and it takes me well over 2 hours in traffic just to get there.
But I think the big thing I've seen is the quality of our shooting ranges out here are much lower than yours. Even in states that are gun friendly, it's rare to see things like e-targets or modern upscale facilities, and the largest indoor range ranges you'll find in the entire country are generally less than 100 meters...also w/o e-targets.
I just think it's a shame that we have this amazing ability to practice this skill but the facilities are sub-standard when compared to countries that are much more restrictive.
@@Furiereindulgente Thanks! It's nice that some places have places seem to put some money into their facilities. I was doing a google search, and I see there are a lot of "Tiro a Segno Nazionale" locations, Is that strictly for members of Olympic disciplines or are they open to the general public?
@@edweiser63 the "Tiro a Segno Nazionale" are the institutional ones, open to the public. They can have ranges for air guns, for olimpic .22lr, for pistols or for long range rifles. Then you can have other institutionals just for skeet shooting, but all of them are for the general public, olimpic athlets have to share it!
At 100yd, WWII surplus M2AP .30-06 would penetrate 1" of steel.
I’m guessing the AP .308 will penetrate deeper into the steel than the .50bmg
Intresting video
I saw a video saying that in WW1 germans seeing tanks for the 1st time took apart the mauser bullets and reinserted the bullet backwards. This was apparently more effective. I think your video makes it clear that turning around the bullet wouldnt matter since all of the energy is dumped in the plate so bullet type and shape is irrelevant. What do you think of this?
It shouldn't make any significant difference. It would make the bullet expanding against soft material though
@@Backyard.Ballistics The presenter was telling it as fact and that it was effective. I think the effect would be as you have shown. All of the energy is being transferred. Without a hard core the shape of the bullet is irrelevant. It could be an propaganda of germany... makes it sound like they had something effective when they really didn't... good for moral while they worked on something else. Like most of these silly ideas if they were so effective then why go through the expense of developing special bullets when the soldiers just need to flip a few projectiles and take out a tank.
If anything I would think a pointed bullet may help with the transfer assuming it doesn't glance off. It will create a small initial dimple which will allow the rest of the bullet material to collect in and expand.
Funny how the .50 bullet material is like cold welded to the steel.
Is thera a differece? I feel like more correct name would be "which caliber is better against steel"
Was that a hollow point or a match round? Cause most of the match rounds I purchase have that tiny hole on the tip compared to the relatively larger holes with ballistic tips on the actually marketed as hollow points I have purchased.
that one was a barnes TSX, a hunting monolithic bullet. It wouldn't have made any real difference against steel if it wasn't hollow point by the way
Backyard Ballistics
Yeah looking at the box it says HPBT in the description of the Sierra match king bullet. Otherwise no where else on the box does it say hollowpoint. Little weird that they wouldn’t say that elsewhere but meh.
any chance of seeing uranium core bullet test?
No uranium containing ammo for portable weapons (including 50 BMG) has ever been deployed, for many reasons that go even beyond its toxicity and (slight) radioactivity. In peculiar designs requiring high density, like SLAP rounds, cemented tungsted carbide is used instead of tool steel.
@@Backyard.Ballistics thanks for the response!! Love your channel!!
i thought this guy had like 2.7 million subscribers
They are 27k instead🤣
I'm looking to move to a European country from America. Seems like the Italian gun laws are good, how do they compare to America. Love to see a video about it.
Can you own Armor Piercing rounds in Italy?
