Great video. I love my muzzle brakes. The biggest two complaints I have heard against brakes are from those who are not shooting. The concussion of the shot, and the increased volume are what people have complained about.
But, as the person shooting the gun, I absolutely love my brakes!
Cheers Joe
No kidding. I always get stuck in a lane next to someone like you at indoor range using the "loudener!" lol
Fascinating! Nothing simple about a projectile escaping the bore of a rifle. Thanks Mark. I really appreciate your sharing of your knowledge and experience.
Thanks Dave, Cheers
Possibly the best treatment of muzzle brakes I’ve seen, thank you!
Awesome. Thanks man
The more you know the more you grow ,so much more to learn Thank you
Cheers Richard
I can tell that you are very knowledgeable about this topic and have so much information running through your head that you get carried away on tangents slightly and catch yourself talking about things that you know will go over people’s heads…it reminds me of myself when I talk about my profession. I can tell you’re a good guy and have spent a great deal of time learning about the art of long range shooting.
Cheers!
Cheers
Thanks Mark,I find it strange that most rifle companies put a radial brake on their rifles, the radial muzzle brakes are a bit "dusty" and not all that effective.I have gone with the KS Arms brake on my 300 WM and its like shooting a 223 now. It used to be 10 -15 rounds and that was it for a while, now I can shoot it all day and no shoulder disruption. Your explanation and video of the projectile and gasses leaving the barrel are saved for education purposes. Thank YOU both.
Cheers Don
Which exact muzzle brake did you get? They have a few options. I just bought a 300 wm without a brake
Thanks for the continuing education. As much as I am frequently entertained, I’m always educated with your videos. Keep up the great work.
Thanks Steve, Cheers
I've watched the development of the m3 Impact air rifle and the cavitation caused by overdriving the slug and it makes sense of what you have illustrated here. For my way of thinking if you are not going to develop your loads etc then you will need a certain amount of luck to use a muzzle break and experience the best accuracy results. The slow motion videos also added weight to your argument. Another great talk. End of day repeatability is accuracy and I don't know anyone more accurate than you. Thanks for sharing.
Thanks Jon, Cheers
Another well explained topic. My experience with muzzle brakes is limited to shooting a friend’s S&W 500 pistol. His 500 had crazy recoil but it was only when I stood about 10yds behind him at about a 45 degree off to the side that I realized how much of the recoil the brake had reduced. As he took the first shot, the bleed off on my side of the barrel literally felt like a hard punch to my chest! I thought that if none of the gases were released by the brake, you’d have an unmanageable amount of recoil… at least for mere mortals, lol!
My rifles are either 22’s or old school hunting rifles so I have no experience with brakes on rifles but that 500S&W revolver showed me the value of one for monster calibers!
Great video, as always!
Thank you Paul, Cheers
Very interesting and informative presentation. Thanks for the slo-mo on the bullet gasses surrounding the bullet. I see why a ding in the muzzle would deform the gas and cause the bullet to weird things.
Thanks Man, Cheers
I really like your videos about muzzle brakes. I’m always interested in physics and I appreciate the detailed description of the mechanics of how they operate. I don’t know of any place online that goes into these topics with as much depth. Awesome video as always!
Thanks Will, Cheers man
I just bought a PSA AR10 in 6.5 and have been researching brakes for a while, this video confirmed my thoughts. Thanks for your time, I wish you had a slow-speed camera on the brakes to see how theory and practicality line up.
Cheers
Been saving up to get a couple muzzle brakes from y'all and a rear bag base because your the only people that get it and don't have top ports on your brakes and there very well made brakes and all of your accessories are made extremely well can't wait to make my order coming soon very informative video thanks guys for making too notch products and are just a bottomless pit of information 🇺🇸🇦🇺
Awesome, thanks Allen, Cheers
It's worth remembering that literally anything you put on a rifle barrel will act as a harmonic tuner, not necessarily in the way you want it to. Could make things better could make things worse. This includes the fouling that will build up in a muzzle device.
I don't have experience with centre fire rifles but when it comes to rimfire target rifles for Olympic style prone and 3-position shooting many of them have foresight extension tubes. Some of these tubes have built-in harmonic tuners as does mine. Allowing fouling to build up and add weight to the tube defeats the purpose of having a precision adjustable weight. I don't clean my barrel every trip to the range but the muzzle device gets cleaned after every single use even if I only put 15 shots through it. Keep it minimal, keep it consistent.
The barrel needs a certain amount of fouling to reach a consistent point. The first few shots with a clean barrel are usually not as consistent as the rest.
Great video by the way. There are a huge number of factors at play here. Something that slightly reduces a gun's mechanical accuracy can help most shooters to use the weapon more accurately.
Cheers James
Had big surgery on both shoulders, use muzzle brakes now to reduce the punch into the shoulder. Nice content as always 😁👍👏
Thanks Man, Cheers
I certainly hope your muzzle brake works well, I will most likely take delivery of it tomorrow.
Love the content, I'm constantly amazed at the shots you're able to make at such absurd distances.
Awesome, Cheers Aaron
Reading the development of large caliber naval gunnery. They actually push a jet of air before the shot to help the air inside of the barrel to move before the projectile. On some tank barrels there are cans half way up the barrel. According to the guys at the ordinance test labs, it serves two purposes. One is to help evacuate the bore and barrel. The other is to have capacity to hold some of the air in compression as the projectile is pushed through the barrel. As the projectile is compressing the air into the can, once it passes the ports the compressed air starts the evacuation. Not necessary now with smoothbore firing winged darts. Thank you for the informing videos. Love them.
Cheers Pete, thanks
I had an angled port muzzle brake on my .260 rem Sako TRG. Recoil was zero, but the concussion of the blast was causing me to start flinching on occasion in 30 round competitions. I removed it and am now shooting the rifle standard, no brake, no suppressor. The recoil of the .260 in the heavy TRG is not significant. Rather a bit of recoil, than the concussion. Which is also hated by fellow shooters on the line. I would like to try one of your "90 degree" brakes sometime. Thank you for a great channel.
Cheers Man, thanks
Great videos, I try to watch everyone, all of them are well worth my time and attention!
Awesome, Cheers
Thanks, Mark. Always enjoy hearing your thoughts.
I loved the high speed video of the round exiting the muzzle.
Thanks John, Cheers
I run a tremmor 2 on my 22lr. Originally just for looks 😂 but I did see a gain in accuracy. Thanks for another informative video 👍👌
Cheers man, thanks
I like to think of a baffle as a sail with a hole in the middle for the bullet to go through. And, because of the physics of supersonic gas flow, a mach disk forms at the bore of the baffle creating a virtual baffle thus making the baffle temporarily boreless to the expanding gas from the burning powder charge. This phenomenon temporarily forces all of the expanding gas to go sideways. Also, a larger surface area baffle/sail catches more expanding gas and mitigates recoil more effectively. Good explanations, Mark. Also, I plan to use flat base, lead core bullets from here on out for better obturation and less pre ejecta turbulence. Combined with one of your brakes, shooting should be more accurate and more pleasant.
Awesome, Thanks Paul, Cheers
Thanks for the video. This helps with many points of muzzle brake effects. Much of what you discussed was what I was trying to confirm from my own way of looking at this subject.
Thanks Jon
Beings that I've shot one of my best groups without one....I still prefer to run one in most guns....even pistols
being a student of yours I fully agree with you on comp design for long range rifles shot in the prone position...
Ultradyne break is superb for a 3gun rig with something longer then 14.5 inch barrel..but put it in the prone position (especially on shorter barrels) it mike Tysons you every shot 😆....
For prone shooting your design is superior. Hawkins precision tank brake is another great option for AR 15 barrels...it's very nice in the prone.
These videos are greatly appreciated 🙏.
Thanks Man, Cheers
One thing about shooting everything can affect accuracy, harmonics, the barrel touching something. I never thought a brake could affect the accuracy.
Cheers
Great! Trying flat base projectiles searching for better groups i can confirm what you said, and this appears on differents rifles that we have used for this test❤thank you so much for all that you share with us! Bye from Italy! 💪👋
Thanks Man, cheers
Very interesting! Thank you. For some reason, I remembered the Browning BOSS (though I don’t recall how many years ago it was introduced). An adjustable brake that allowed you to tune your barrel harmonics was an interesting concept. Oddly, I’ve not heard much about it lately.
Thanks Lane
Explains the "target crown" which is usually 11° angle, probably having to do with aerodynamics of the gasses out of the muzzle as the bullet base breaks the 'seal' of the bore.
The slow motion video footage sure was helpful, seeing this high speed gas flow zipping around the bullet as it's exiting the muzzle. In relative terms, the bullet is a slow heavy object and the expanding gasses are like tornado winds blowing around a farm grain bin.
Cheers
Thank you for sharing your knowledge. Real difference between pistol and rifle muzzle breaks. Run vertical ports on my pistols, but not on my rifles.
More about compensators for muzzle rise on hand guns, Cheers
Great information! Just the other day I was fighting with an AK pistol that has always shot kinda terrible and I pulled the muzzle brake off for something and realized that the bullet was just kissing the inside of the muzzle device... The threads not concentric. Shot it bare muzzle at 50 yards my zero was 9 inches higher and grouped way better! Fixing to send it to get rebarreled because there is not enough to left to do anything with
Cheers
Much appreciated M&S keep up the great work guys 🇺🇸🌟🇺🇲
Thanks Tate
well explained and is on point with my expirience I've got in 20 yrs of brake making 👍
Thanks you Andrew, Cheers
Im by far not a firearm expert, i only worked as machinist and mechanic, mostly doing lathe work and drilling, deep hole drilling with gun drills etc. But i have to throw my mechanical nonsense into here. Clear things up for me if im wrong, i'm always happy to learn stuff!
From my understanding the crown on a barell is more important for accuracy then the overall condition of the barell since it's the last thing giving the bullet a "nod" into a specific direction.
I assume, when you have a really well machined muzzle break, say the gas distribution inside the thing, and in front of the bullet is even and the tolerances are on spot, i'd opt for anything 0.00078" or better. It's the same as with space travel. If you aim your rocket 1° in the wrong direction you probably miss the moon by like 15.000 miles. (thats just guessed, don't nail ne on that distance)
Means the more effort you put into having an accurate machined rifle and properly loaded ammo with maybe machined bullets that are within very tight tolerances, the better you gonna hit stuff the further it is away.
Then i don't see why accuracy should decrease except you are moving say velocities outside of the "spec" for the ammo you are shooting?
But then come things into play like barell harmonics, if you put weight on a long thing stick, it will bend, if you build up pressure and heat inside that stick that then moves to the outside to dissipate that energy from the barell again, then the heat will start to affect the material and it will start growing in whatever direction the geometry of the thing allows.
Heck even gravity gonna pull on the thing 24/7 so you could actually account for even for that when construction the barell with the fitting muzzle break.
You would have to tune the system at once tho, or into one package. Because if you change one bit the other wont fit perfectly anymore.
But yeah i think since its physics you can take everything into account and still have a "perfect" shooting rifle and imo it should even be more accurate if its properly designed with a muzzle break then without. As close to "perfect" as one might get in reality that is :)
Man i was writing before really watching the video, guess i wasn't that far off! But again if im wrong anywhere, if anyone read this wall here, feel free to clap me back into track! :D
Thanks again for taking time and explaining stuff like you do.
Always enjoy listening to you guys!
Cheers
My Encore barrel in 7 mag has the factory “muzzle tamer” on it. Ports are in a V and angled back. Permanent install. Great on recoil reduction and keeping the scope down but feels like getting punched in the head. I would like to get it removed. Great information Mark!!!!!
Thanks Man and FYI have a Gunsmith look at, they might be able to sort out, cheers
Thanks Mark. Great vid. Respect from Melbourne.✊🏻
Thanks Matt
Excellent explanation of all things muzzle brakes 🤘🏾 keep up the great work .
Thanks Ricardo. Will do. Cheers
And another great presentation from Down Under!
Cheers Allen, thanks man
a heap of good info , with all the myths busted . thnx Mark.
Thanks Fanie, Cheers
Great content - all shooters should learn something from this. Thanks.
Cheers man, thanks
Thanks Mark and Sam. Great info and video explaining muzzle breaks.
Thanks Dwayne. Glad you liked. Cheers
Thanks for expanding the brackets on it Mark.
Cheers man. Glad you liked.
I really enjoy learning about the physics of projectiles.
Cheers
Good day to you and Sam .. thanks for the information ..
Thanks Mark
Great video very informative, keep the videos coming a fan from the US.
Thanks Donald
It sounds like having narrow port (less than the length of the bullet) is more efficient and more accurate.
Have you considered roughing the surface of the brake. It would convert the laminar flow to turbulent flow. Blast would dissipate faster.
Love the videos; great content
Cheers
I’ve had a bunch of people ask me why I’m using your muzzle brake. I’ve never had a technical answer for them. Now, I do...!!!
Thanks Tommy, Cheers
I use witt machine SME devices, I can take the blast can off at the range to save my shoulder and when I move to hunting with the platform I put the shroud on and no feeling of a pencil being jammed into your ear when you shot your food. And I've found the muzzle directing gases away from the bullet as it unqaurks from the barrel seems to help with precision, or maybe it's just recoil is controlled better leading to better accuracy, either way it seems to have helped on all the rifles I have fitted them with.
Cheers
The rifle moving during recoil is an interesting thing, I've seen this myself where I can influence a measurement by a large enough value to be a real change. Take a big bore airgun shooting in the 800fps range, brace it firmly and get a value, now try another where it isn't braced as firmly and can move a bit, and you should see a lower speed. I've seen 10fps difference with my .357 airgun by pulling it tighter to my shoulder.
Also I like how you explain the brakes, makes me think I cut mine "correctly" when I milled out a block for my .510 airgun. It was just scrap aluminum I had on hand, but it is chambers with outlet 90 degrees to the barrel. Seemed to work OK but I haven't shot this rifle enough yet, only gets 3 shots per fill and about 8 minutes to refill, so easy to spend a lot of time waiting. Need to get it over a chrono too.
Thanks Mna, Cheers
An idea for you you to try, I don't recall any of your videos exploring it, is the have a large straight port as the first port, and the perhaps a 15 degree rearward port for forward drive on the rifle. The gas gas interaction should still provide a mostly perpendicular gas flow, so no over pressure at the shooter
Yes used them, and for gas flow yes, for percussion, all the logic all still applies, Cheers
I tend to agree. I've noticed differences in my own anecdotal shooting. However many people will say that it makes no difference.
Cheers Man
Air stripper's are a thing on target air rifles, so your correct no matter what the scale they have effects.
Hopefully one day you lot get suppressors, then you can go through testing all over again.
Thanks Mna, Cheers
Great chat! Thanks for sharing, cheers!
Thanks Man
Barrel resonance is a problem for me right now with my brake on. It is an Aero VG6 Gamma and did reduce recoil very well. What I've discovered though is that my groups are actually better with a Magnetospeed bayonet on than without. If I cannot find a way to manage resonance, I'll have to switch brakes or just put up with a little more recoil.
Thanks Scott
Hey Mark & Sam, thanks for the info.
Thanks Phil
Always excellent videos. Thank you.
Thanks Col
I have an MDT comp brake with ports on the top. With the brake on, it seems to cause the bullet to have a different trajectory than all the calculators predict. When i take the brake off, the gun matches the calculator exactly. (I would rezero the rifle every time i add or remove the brake) Have you ever observed this with any of the brakes you have used?
I've come to the conclusion that any brake i buy from now on needs to be symmetrical left/right and top/bottom.
Great video!
As explained in video, brakes like that cause barrel direction change, Cheers
I will just use one of your muzzle brakes problem solved cheers Yogi 👍🤘🇦🇺
Thanks Brett, Cheers Man
I'm having accuracy issues with a quite new Tikka T3 X Tac in 223 and I was actually considering trying it without muzzle brake. Up to 100m, 5 shots in one hole, but at 300m I do not retain the MOA accuracy expected. On the other hand the € 1,200 Sabatti 308 without muzzle brake did not pose much problems to get well under 1MOA at 300m. I got the Tikka to push to 600m but I'm still a long way off.
Thanks Jon, Cheers
Wind?
@@prone_wolf8871 No, None. This is a rather sheltered shooting range and I like testing loads and new guns in it.
Absolutely excellent! Thank you.
Cheers Man
I have had great luck w my radial muzzlebreak. Def reduced recoil. And its just as accurate as wo. Diff point of aim on vs off but both configurations are .5 moa or so
Just no good for prone in any dry out door conditions... Cheers
More great education Mark, thanks!
Thanks Geoff
This is great work! Keep it up!
Cheers
thank you . brilliant explanation
Cheers Joe
Always helpful, thank you
Thanks Daran
I have a Muzzle Brake on my custom 6.5x55, reduced the recoil substantially, I can't say weather it has affected accuracy as it has always been on the rifle so nothing to compare, the only problem is a certain association won't let me shoot at their rages because I have a Muzzle Brake.
Thanks Man, cheers
Good stuff Mark!
Cheers Jason. Thanks man
Hi Mark & Sam, thanks for the info. I have a request, can you please explain the attachment I sometimes see attached to the end of the scope (like the one behind you). When I was asked I assumed it was probably a periscope type attachment can you please educate me on this.
Thanks and God Bless
Look up "Charlie Tarac"
@@markandsamafterwork thanks Mark, I’m not as dumb as they think I am, but as I truly believe and say “don’t assume, ask first”. Cheers and God Bless you and yours
I always enjoy your videos and the information . Do you do any testing on terminal performance of different bullets at 600 to 1000 yards if so I would love to hear your thoughts on bullet choice at extended ranges for hunting.
Cheers
Thanks Mark!
Cheers
Have the 4 port air bypass diverter. Should the barrel crown be into the first port, or is it OK to be back into the threads?
Ideal is crown is level with opening of port, but fine is a little short, Cheers
Great content , as a question what make is your bipod ? do you manufacture them for sale ?
4aw-store.myshopify.com/collections/4aw-bipod-mounting
Hey mate, do you ever get any crud built up inside the muzzle brake ?
I have only ahot 12 rnds thru my new ruger hunter with the magpul stock and muzzle brake. And i see something like lead inside muzzle brake and even on outside of crown.
Yes any muzzle devise will have little carbon and copper over time, needs cleaning if builds up enough, Cheers
Hi Mark, great video and very informative as always. Are you able to talk about how if at all critical the internal diameter of a muzzle brake is? I notice that a lot of muzzle brakes on the market are set for larger callibres such as 308 and 338 but claim they work on the smaller callibres too. But at what cost?
Doesn't make a lot of difference in performance, and allows for thread inaccuracies, Cheers
I love my strike industries king comp on my sr-556 it really tames the jump of my piston rifle so yes it is more accurate.
Thanks Man
Thanks mate ... a 'similar ' topic we discussed at the range, Sunshine Coast, today was are stainless barrels more or less accurate. We had 2 standard Tika CTR's, .308 with barrel material the only variable ... shot the same ammo, ADI, swapped rifles and got the stainless fractionally more accurate. Thoughts? 🤓🇦🇺
We have videos on barrels, but all sorts, good quality and bad, lots of details to it, what steel their made from does not make a difference to accuracy, Cheers
Great content thanks for sharing
Thanks John. Glad you liked. Cheers
I was thinking of putting a muzzle brake on my deer rifle. And if I do this if I understand you correctly then I may need to re-sight my rifle because the harmonics of the barrel may be changed? Yes or No???
Should always test, Cheers
it definitely reduces my flinch on my 300PRC :) thus more accurate (but not due to the device but me)
Awesome, Cheers
What do you know about rebated boat tail bullets?? Example would be Rocky mountain bullets.
All on the channel ua-cam.com/video/FKPR4gaieSg/v-deo.html
Awesome video
Thanks Sterling
Muzzle brakes for me is comfort for recoil, I get better rifle handling, recoil management...which is better trigger control and sight picture concentration or pinpoint accuracy I can stay on the rifle and get better follow through...if that makes sense...Great Vid
Thanks Man, Cheers
Hi Mark have you published anything on barrel tuners that you could direct me to?
We dont use them, but have a couple on harmonic's, use the channel search, Cheers
@@markandsamafterwork thank you
Aaaaand they look very very cool ;-)
Lol, Thanks Peter
Do muzzle breaks affect barrel harmonics and accuracy?
Can do, all in video!
I've got a Savage 110m in 22-250 with muzzle brake,,I don't find any difference at 200 yards ..But..big difference in less recoil..
Cheers
cheers
Cheers
Have you shot with suppressors much Mark?
Not legal here
Slow motion really shows the unburnt powder pellets exiting the muzzle.
Yep, Cheers
And hybrid short, fat, silencer / brakes? Best of both worlds potentially?
Cheers
How about break tuners?
We never found a need for tuners, but all the same deal, with a tuner included, Cheers
👍😊
Cheers Chris
👍👍
Cheers
If you go to something like the EC tuner break, you’re better off in most cases
Lol....
🎉✌️👍‼️
Cheers
sometimes i really have to police my urge to giggle when you say "retardation" LOLOLOLOL
🤦♂️ Cheers
I think you are more accurate with brake . Maybe not the rifle
Cheers
Good morning Mark n Sam. Hope you all are fighting the good fight over there ! You have all of our support!
Cheers man, thanks
