Take a Ruger#1,Win92,NEF Handi Rifle . . look how they lockup . . big difference. What makes the AR able to handle some of the powerhouse chamberings that it does is the gas system. I have been told by firearm "mechanics" that if an AR was a single shot,with no gas driven bolt unlocking (dwell time) it would blow itself up. Maybe not with a 223/5.56 but with one of the higher pressure chamberings WITH quite a bit more case head thrust.
IMO . . . 8grs over . . . you got lucky . . . this time. --- SAWMAN
Thanks for the info, normally I'm more careful when reloading and double check my numbers. That's what I get for being in a hurry.
