All about Muzzle Brakes (info video) 

I love how much information you give out.

i recently got a lightweight .300 win mag - it was extremely uncomfortable to shoot from prone- to the point where i was thinking about selling it, and was really regretting not just going with a .308-- i just put a 4aw 3 port brake on it 2 weeks ago and it is now my favorite rifle to shoot- it no longer kicks up dust in my face or gives me a headache after 10 rounds shooting from an open area that has a roof overhead...well worth the money and the quality of the brake is excellent- it really does work as described.

To you and Sam, i’ve been watching you guys for a couple of years. Thank you for your hard work on ULR shooting. I have learned a lot from your efforts. I have become a more accurate shooter. Thank you very much👍🎯!

Hi Mark praying all is well, I am so happy you said what you have about the break not making more noise, I have argued this with a number of people. Cheers to you and Sam

Hi from Northern Wisconsin, USA. Love the ELR. The initial expulsion through the muzzle of the air column in front of the bullet is something I had not considered before. It has much lower mass and velocity than the gas coming after, but yes, it should be considered. I’ve been thinking of tasking my son to model this for me. If I ever do, I’ll share it. He’s the thermodynamics guru in the family, I’m the radio guy. Cheers

I love these videos. Extremely informative especially for me where not many people i know have all that knowledge and are willing to share it. Much appreciate the videos can't wait to see more.

Wonderfully informative video, you shed light on some aspects I never considered. I have only ever used the brake that came with my precision rifle, but I hope the manufacturer knew what they were doing when they paired it with the rifle! 😅

The two things I was looking for are reduced recoil and group size improvements ! Now comes the search for the right muzzle break for my AR , thanks for your explanations , it was informative !

Thank you for all your insights.

Thanks for all the good advice and information.

Lots of great info! I had a PVA (jam nut style) muzzle brake years ago that wasn't tightened enough, and it started changing the POI drastically.

Great food for thought Mark, I built a 260 rem on a long action with a 25" 1:7 twist to handle heavier bullets. 90% of my shots are standing or kneeling from150 to 350 yards. It has very mild recoil, trying to improve it a little more. At 6'2" and 65 years old those hills and valleys seem a little bigger than they used to be.

As far as the "tap on the nose" phenomenon I have a CMMG brake on an AR that actually clears my sinuses quite well when I shoot. A rather pleasant side-effect for sure.

I have observed that the most knowledgeable people preface their comments with phrases like "What I've found" or "Just from what I've seen", expressing that they feel there is a lot they don't know.... I'll take advice from people like you LONG before someone who says they are an expert..... Thanks to both of you and greetings from Oregon.

This is an excellent video. Thank you so much for sharing your experience Sam. Much appreciated!

Yea guys!! I need to invest In a four port for my 338 Lapua. You guys are the best. I sport my 4A stickers on my Pelican case. Always reference and speak well of you guys.

Really interesting and informative video. I’ve always been interested in the physics of how they work.

Thank you for explaining how these work!

Very valuable information mark!👍

So much knowledge in this. Wow... love this video.

Very nice video Guys and good information on muzzle brakes and how they work.

Everytime I think I know something, there's always a lot more on this channel. 👍🏼

This is extremely interesting. I wish you were able to do this with suppresors too. Extremly informative. Thank you

Hi Mark, as Marc said i would have never even thought of the compression of air forward of bullet so one more on the list of things i have leart from you. As far as brakes go , your spot on - the less felt recoil the more blast / percussion in the face so it is a trade off.My mate has a 223 Ruger Scout and for a small calibre that doesnt really require a brake it is the nastiest thing i have ever been behind - if your any closer than 10 foot behind it whist someone else is shooting it literally bitch slaps you in the face with the percussion , when he shoots this gun i make sure im at least 20 ft behind. In contrast i have recently picked up a 450 Bushmaster Savage 110 with factory radial brake ( obviously not for prone shooting ) and i gave the missus a shot with myself 10 feet behind to keep an eye on her and expecting a hell of a slap it was bugger all compared to the Ruger 223 , makes no sense to me but it has to be in the brake design. My LA102 308 has one of your 3 port brakes and same deal , i can stand fairly close behind without getting that nauseating percussion that just feels off to your body ,and shooting prone in dusty dirt the dust cloud is a good two to three feet off to each side and not a problem unike a cheap one i got off ebay which i shot once and that was it. The 308 recoil is no issue but where i struggled was when shooting by myself and i could never see impact out at longer ranges - very frustrating . Even at 100 m i ave tightened up my groups more than 1/2 once i had your brake on . 1 i can see impact and 2 im not flinching where i was before i had break on. Interesting what you say about top ports to tame muzzle rise = this would have to change with every different bullet weight and charge yea , so would never be consistent i guess. You and Sam keep up the good work Cheers Rob PS Give me a yell if you want to borrow the 450 for a crack at 1000yards - probably do-able if you aim at the moon but you of all people would probably pull it off lol

Great stuff mate , top info thanks mate

This was such an educational vid. I thought muzzle brakes worked soley on the gas pushing the rifle forwards. Not on the gas hitting the panels. Plus your humble way of presenting information. You don't come across as a knoe ot all. But only presenting what you have experienced. Thank you Mark.

I use 2*12 boards placed angle forward and canted up to deflect the muzzle blast from the break away from me and people to the sides. Works surprisingly well and doesn't anger my fellow shooters and spotters. When shooting prone I will either wet down the ground in front of me or use a canvas tarp to keep the dust and dirt from becoming a giant choking cloud everytime I fire.

Excellent information, thank you. Just got into more high-power precision competition with a bergara 6.5 creedmore. It was the first rifle I'd used that was threaded for a brake, and I was curious about the mechanics of it. Well delivered and clear information. Thanks!

Bravo! Great video!

Nice explanations has always. Maybe on day you will talk about sound moderator and their effects on precision shooting. Thanks for yours videos.

Appreciate explanations with muzzle breaks. Blessings

Thank you sir. I want one of your 2 or 3 port brakes so bad for my Ruger Precision Rifle, just gotta save my pennies!

Love it as always. This channel, johnny's reloading bench, ted's holdover, Joerg Sprave and a few others are my favorite RU-vid channels.

Great video very informative to. Be safe and GOD BLESS.

Very good video!! Thank you Mark! I am completing my Remington Sendero SFII chambered in .300 RUM. The rifle at point weighs around 14 - 15 pounds with scope and bipod on it. The .820" varmint contour on the barrel helps by adding the additional weight. I can definitely tolerate recoil from rifle chambered in 30-06 without scope and bipod weighing around 8 pounds. My question is, Would you know approximately how many foot Lb. of recoil this rifle will generate at 14 - 15 pounds? I also hand load this caliber using H1000 propellant with 180 - 210 grain projectiles. Thank you,

Muzzle Brake pull off, there are alot of things going on there. The U.S. Army kinda figured it out. They did their homework. The Army figured out that some of the otherwise good shooters had problems when getting behind bigger bore rifles one thing is natural point of aim and laying straight in line with the rifle. another one is a cold column of air in the bore being pushed out and hitting the baffles causes the muzzle to move before the bullet exits the crown. Alot going on there.

The best way I found to describe shooting an early Barrett 50bmg is like getting hit in the face with a basketball somewhat lightly!

very interesting, thank you Happy New Year

Thank you for the research

I shot a Barret 50 bmg with the muzzle break pointing kinda backwards and it felt like I’d been hit in the nose but my 300 kicks harder than it did. Course it weighed 33lbs with the scope.

Came for the knowledge and stayed to hear Mark say, "main blast of gas." Just put a brake on a gun I'd been shooting without a brake for a few months and was surprised that the POI changed by about 3" at 100 yards. Shot groups stayed the same.

good info.

Great explanation loads of info! Please see if u can add detail views of muzzle breaks as the black shirt and dark breaks can't see all detail on them or zoom.

Crap I may have already replied to this some time back. Hope you get this. Great video on brakes. I'm going to need to look and see if you have videos (or a video) on suppressors. I'm in the market for one, don't own a single suppressor and the laws of the US with suppressors piss me off, so I'm trying to figure out what direction (brand and size) I'm going to go.

Once again showing your expertise. If i may, ask 1 question.. On my howa 1500 in 6.5 cm i have a brake and bipod. It still has upward and twist to the left while firing. Would addind a port or two to my current brake on the top help buckle it down or is there a way or system for weighing it down for everyday bipod use. Say possibly a hook and weight to hang on the front strap anchor point or oh the bipod itself. Free floating bedded barrel balanced harmonics with tuning so dont want to touch the barrel. Also to be noted, my brake is very similar to the one at 14:30. I appreciate your time and knowledge, thanks.

Another very informative vid mate. I have never owned a rifle with a muzzle brake. With that in mind if I was to want to give one a go to see what I thought without going to the extra length of taking into a gunsmith and getting a thread machined on. Do you think one of the breaks on your far right ,(iam pritty sure you said are from hinterland shooting) would be a good start to try on my tikka t3x varmint in 308win. If so is there much involved in fitting the brake?

Hi thanks for sharing your thoughts and knowledge. Just wondering,do you have an average % for the size of hole compared to bullet diameter. As in when is the hole too large. Always enjoy your videos, thanks again for sharing your videos.

Fantastic video mate! Really explains a hell of a lot on the muzzle brakes. I’m about to get a .308, using for target and hunting. Will be off bench, prone and shouldering so would you have a recommendation for me as this is my first bigger cal rifle I’ll be owning. 🤙🏻🇦🇺

I once shot at Bisley alongside a guy with a radial muzzle brake on a short barreled .223 which made me face away from it when it fired, as I could not only feel it on the face but also through my skull as though my head was a drum. Very unpleasant indeed

Hi Mark Really informative; cheers. Question for you. Here in the UK 'silencers' are the norm, (not I understand in Australia). For me, where varminting is my thing rather than ELR, I would chose noise suppression over anything else. That said, control of recoil is a huge bonus. Do you have any experience in the field of silences and which may offer the best sort of balance between noise suppression and recoil control? I apreciate that this may not be your field of things given the differing regs between our countries. All the best from sunny England.

Hey mate. Most of the people on my local gun club don't like muzzle break because it's too loud the say. Hope they see this video

Very helpful Thankyou. Where do you sell your custom brakes? Would love to get your advice. Thanks

Hi Mark, you explained that a good muzzle brake would make the rifle recoiling straight. Is it possible to adgust this effect by changing the height of the buttplate ?

Agree on the concussive blast. Terminators are the worst muzzle brakes I've ever used for that exact reason. And yep each to their own, but I shudder if I ever have to shoot or be anywhere near a mate's rifle with a bloody Terminator on it.

This might be a dumb question but would using a 30 cal brake have an adverse affect on a 6.5? From what I've read so far I don't believe so but just wanted your thoughts on it

When building your muzzle brake, what angle of the ports have you found to be the most effective? Roughly, of course. Thanks.

Haven’t tried it yet but I just installed a clamp on muzzle brake

What’s a good muzzle breaker for a 6.5 creedmoor?

Great video! Are you in the USA, or down under?

The problem you will have with ports at the top is if you OVER compensate, too much gas coming out the top will drive the muzzle down past where it started, with side ports if you have too much gas the muzzle stays natural as there is equal force on both sides.

My theory on a top blast muzzle brake is pressure moves faster than a bullet and will put pressure on the bottom of the bullet affecting accuracy when it leaves the barrel. Does this sound right to you?

Aluminum vs Titanium vs Steel vs Stainless.?

Very interesting but most people want to know what the difference in foot lbs. The muzzle brake mak on there.particular caliber

While you are absolutely correct about muzzle brakes not actually being louder, that doesn't alter the fact that some clubs, like mine, prohibit their use. Apparently on a conventional gallery range, muzzle brakes scan really annoy the shooters on either side of you.

How much US dollars do your brake go for me to purchase

4aw in spanish pleace

I don’t like muzzle breaks. I’m looking to keep my fellow shooters hair in check 😉

Feeding the algorithm. This isnmy 5th 6th watch through.

🤌🏼
