It’s one of my top 3 sites for getting real life feedback with useful info to follow. I can read something online and copy somebody else’s claim to another forum. These guys always provide pics, videos and realistic numbers.
JE I appreciate your detailed explanation. I always learn something in these forums.
From experience, I might disagree with the 45 degree angle back ports. I don't think the shooter suffers from increased sound shock. People around the shooter will. I still remember the first time I shot a rifle with the BOSS. It did not affect me, but everyone else on the range complaint
Barrett Brakes = The Tossed Salad Effect, That's what we called it back in the day, The McMillians were worse, it felt like you couldn't breathe for a second or twoWhen I first became interested in muzzle brake design was many years ago. I am a veteran and did not like the abuse that service men were subjected to when shooting the 50 BMG. many claimed sinus problems after 20 to 30 rounds, the spotters had it worse.
When I bought mine I was told not to shoot it unless I had both ear plugs and ear muffs. Recoil was marginal but manageable. My goal was to reduce the noise, recoil and the signature. (If possible)
The first step was to shoot it without a brake (Bad idea) . here are the results
50 BMG Barrett M82 A1
Rifle weight 33 pounds.
750 grain Hornady A max.
250 grains US 869 or 248 grains of H 50 BMG
Velocity 2944 ft/sec
Recoil without brake = 117 ft /lbs
With Barrett fish gill brake (Backwards angled ports) = 64.7 ft/lbs
With 5 port Assassin = 43.3 ft/lbs
The concussion problem was improved to a level allowing the use of ear plugs by them selves without them being blown out of your ears from the pressure wave to the sinuses (This actually happened to one of the shooters shooting without both the ear plugs and the ear muffs).
The flash signature was reduced to almost zero and the gas impact to the spotter was reduced significantly.
The 5 port Assassin has the same volume as the Barrett brake so there was no advantage in volume of ether type of brake. Maybe the Barrett brake is not as efficient as other angled port brakes, and although a 21 ft/lb improvement may not sound like much in percentages but considering that is the average recoil of a 30/06 I could tell/feel the difference.
To date I have not found an angle brake that would equal the Assassin with progressive ports or straight ports. Some have been within 4 or 5 ft/lbs but the blast effect rendered them unusable compared to other designs.
This information is arrived through testing and is the reason I believe it. In theory the angled ports should be better but with the bore hole in the Brake working against the ports, efficiency of the brake can more than offset any advantage it may have.
Just my experiences through testing

Have you shot the same rifle back to back, supressed vs braked? Brakes provide way more recoil reduction over the can.How does a suppressor reduce recoil as much as a brake when the gas is not evacuated? I know gas is diverted sideways but it's still contained in the can which is attached to the gun. Are brakes with blast shields still efficient?
The concussion from my 338LM I do not notice unless I get careless and do not install my plugs and muffs. I have noticed that desert rocks in a 15 foot radius are cracking and breaking.concussion hurts after having some close explosions your insides hurt and the next day you will be sore all over . You will see people with internal head injuries from it . I have seen where people and animals were just dead showing no signs of injuries to the out side of the body from concussion . If you are receiving sinus damage you also are receiving some amount of trauma to your brain , I personally don't have enough brain cells in use as it is . And that sir's is why I believe in doing the research and making the improvements to things such as muzzle brakes , A good design helps and a bad design hurts more then some will ever know . I have only had experience with one brake and it was a bad design so it hurt thus I haven't tried any more and is the reason that this thread is so interesting to me Thank You to those that test for my good . Now that my neck and back are fussed I can't take much recoil a 30-06 is about as much as I want to have and I have hearing aids to hear well now as well so even with them out , plugs and muffs in and on I don't want much in the line of higher decibels either but still I enjoy and want to shoot so again thank you to those that research such things as breaks .
I use APA (fat, small, micro) Bastard breaks and I have never had any of the issues you have had but I'm also young and dumb and maybe I just don't notice it but APA is one of the top brands used by the pro's at PRS and I would think they wouldn't use it if it gave them headaches and face fulls of . Also I have one rifle that came with an SLR SR-30 muzzle brake and that one has been fine as well.I need recommendations on a new brake.
I have some of the best in the business as far as less felt recoil but I can’t handle the blowback/concussion on my bigger guns. I can shoot 10-12 times and I have a headache and a face full of every single trigger pull. I’m looking for a brake that has less blowback. I can deal with some recoil and noise is not an issue but I can’t do much more of the ports blowing directly in my face. I may sound like a whiney baby but I have got to change something up...
