Re: What grain of .223 ammo for suppressed
If I was doing a lot of mag dumps, I would probably go with the 62gr steel core penetrators. A somewhat popular belief that is through heavy suppressed fire, the lead inside of of the bullets out there will melt causing the bullet to be unstable coming out of the barrel. Having said that, I have gone through about 5 full auto mag dumps through my Ops Inc 16th in less then a minute and not a single baffle strike. I have done this a couple of times and it was all done with 55gr XM193.
