AA Tank Brake Muzzle Blast Issue

[RiskyBusiness]

Hey guys, not sure if this should be in the reloading section or not but hopefully some of you have experience in this. Im shooting a 50beowulf with the AA tank brake and im getting particles flying out to my side, its not just wind because i found needle like holes on a piece of paper that i placed on my side to see if it was coming from the brake or the ejection port. my brother said it felt like a gust of *****ly air hit his back as he was turned away several feet behind my to my 4 o clock. Could this be unburned powder, oil, pc lead, or what?

My guess is unburned powder because im using non magnum primers? thats the only thing i can think of right now, but its very unpleasant for others nearby shooters i wont take it out again in public until i figure this out.

Reload according to the loading manuals.

Use magnum primers when the saami spec calls for magnum primers.

Brakes- aka - blast enhancers redirect pressure to the side or rear...

They can blow out ear drums and hurt items to the side of the brake or to the rear


Not sure I understand your question

Mostly wondering is it normal for brakes to spit out projectiles from its sides or is it supposed to be just a pressure wave of gasses/air

It could be debris from the bench or whatever you're using as a rest. When i shoot prone, m .458 Socom leaves a three leafed clover of weird ripples in the dust from 4' ahead of the muzzle all the way back to my hips as if I'm in a 45* cone of peace and the rest of the world has hell falling upon it. It kicks up everything but pebbles.

That is normal - especially if the ammo has too slow of propellant or bullets that are insufficiently crimped.

yeah normal where do you think the brakes directs the gases? that's what comes out plus powder and other debris.

Damn so it's actually a concern for safety of others to be wearing eye protection if they're around me. I'm still going to pick up some magnum primers just to see if I can minimize some of that powder debris being sprayed out. Also because I'm using pc cast lead I can't go further on the crimp as I am or I'll start to pierce the lead

Man how could you continue to shoot with a slight breeze that dirt comes back into your face lol

Would you call rl7 a slow powder?

I use it in .45-70 so it might be a little slow for your use. It's easy enough to load up a few test rounds with a slightly faster powder to find out..

FWIW, you might consider trying a "low flash" powder (like Accurate Arms) as it leaves fewer unburnt powder kernels. Also, there are some muzzle devices available that operate as a comp, yet have a sleeve that you can add to make them more of a linear comp (with the sleeve installed).

Truth is that you need to give more consideration to unburnt powder kernels when you are running a gas impingement action. It's dirt you don't need and can typically be eliminated via better component matching. It's just all part of reloading to find the best recipe.

It's not a joy BUT it's also not how I often shoot that little hammer; only when I was sighting it in. I took a hog with it offhand at 70+ yards a few weeks back and THAT'S when it's a pure joy. Boom. Pig opened its mouth, took a step and her legs folded. DRT.
