    Re: What would cause this kind of compensator damage?

    I can't see the pics very well since I'm on my phone but is it possible that it's just erosion?
    This was taken from BCMs website regarding their comps:

    Please note: The combustion gasses exiting the muzzle of a rifle are extremely hot, traveling at extreme velocity, and contains not only burning gasses but solid particles of unburnt powder as well as metals from the projectile. Due to the inherent nature of steel, it is nearly impossible to survive unaffected in this environment when directly exposed. The high temperatures begin to make the steel more malleable, which allows solid particles and pressure waves to deform and erode surfaces upon exit.

    Hmmm..the pics are clear...the compensater has taked a hit internaly...however much/some of that damage does look like erosion

    Understood. The only pic I could really see was the first one.

    I think that the reason you didnt see any funny holes on paper is maybe because bullets that struck your break didnt even made it there! I would really like to see you shoot some paper at close range with those loads.
    Either way it goes, sucks that you have to go through the ordeal!
    I'm gonna set up a target at 5 yards and 15 yards right behind it. I'll see what the rounds are doing during their path.

    There is definite erosion on both baffles, I'm trying to figure out why the second baffle has strong impressions that are not uniform.

    Awesome thanks, also see if you can take closeup pictures for us.

    No. The bullet was likely still somewhat intact and hadn't come apart yet. It made it through the first chamber before getting squirrelly.

    It's happened to me, but in my case it was a bit spookier, as the rifle was a 50BMG.. Had purchased some pulled M33 ball bullets and loaded them up as plinker rounds.. Took a shot at a rock about 400 yards out and felt a pin prick in my off side arm. Had a tiny sliver of copper that barely broke the skin... Took a look inside my brake( rifle is McMillan M88) and clearly saw an impact on the inside, which left a small crack right at the exit hole. Turns out the lead plug at the base of these bullets can come loose. No problem in a machine gun but something with a break can cause issues...I shoot the Hornady amax now.

    He's a good guy. Very knowledgable as well.

    It takes a little bit of time for a bullet to come apart. It was likely still within the tolerances to fit through the first baffle, but had expanded enough to strike the second.

    There is tremendous centripetal force on a bullet. I've blown up 40 grain bullets with my 220 Swift by pushing them too fast before I figured out that heavy for caliber bullets are generally better for most applications. And that's with a 1-12 twist well north of 4000 fps.

    1-7, 1-8 or 1-9 @ 3100ish fps is a lot of rotation.
