Recently purchased a 16" .300 BO AR and when I had it at the range this morning I had several blown primers. Some the whole pocket blew out (about 5), some just the primer blew out (about 10) and some had no problems (about 15). Thought it best to stop the range session at that point. Could this be an ammo problem or more like an over pressure/head space problem? I do not have the gauges (or experience) that I have read about others using but would this be a problem that a gunsmith would need to fix?
Thanks for the help.
