guys just a few updates on what is going on with the Muscle brake, this page will give you cartrige descriptions/applications for the different sizes.
Center Shot Rifles - Products / Sales - Muzzle Brakes
The biggest problem I run into is guys with factory sporters and they end up with a barrel to small in dia. to fit the 5/8x24 tpi thread tennon, of the standard 3 port muscle brake.
2 choices, if the gun is a 30 cal of 300 wsm
capacity or less the mini still works awsome on those sizes and smaller. (9/16 x 24 tpi) I have minis on my 308 and 7rsaum and they work great, I put one on a tikka T3 300 wsm and shot it, worked great. 338 don't even bother with the mini.
2nd option use one of the CSR brakes very simple common design but thread tennons to fit smaller barrels as you can see on the info page. recoil reduction on par with the muscle.
I have never said the Muscle brake is more effective at reducing recoil, But I do make the claim that it is the most user friendly and pleasant brake to shoot. And I have gotten enough feedback to say that it reduces recoil better than a Vias or a
JP. Read my testimonials for feedback.
NOW the NEW info/design. I have been working with Benchmark barrels as they have the conections to deliver the brake to Canada and Austrailia. They are the only other manf. licensed to Manf. the Muscle brakes to my specs on both materials and design.
What they have done is taken the 3 port slabbed brake and made it indexable by the user, they added a slot and a socket head capscrew into the design so a pre-existing barrel threaded 5/8x24 can have the brake screwed on and locked down, level, reaming or boring the brake for clearance is still needed. And may be a service they offer before shipping. You can call Chris at BenchMark Barrels for details.
I have one and will post up a pic tommorow.
On the sound output, I hesitate to make any claim, I have used a decible reader, and done some testing of braked and unbraked rifles. I recomend ear protection regaurdless of what you are shooting. I will only say this, In the past I have shot braked rifles forgetting to put plugs in. (even the muscle brake as you can see in the first shot on the youtube video.) If I ever do it again I hope it is with a Muscle brake.
You guys that use my brakes, I do thank You.
