Went to the range today to work up some loads. With some of the hotter loads (still under max suggestions) I had 5-6 blown primers. Not pierced, the primer actually blew out. The brass was LC 07 and LC 08. My friend was also shooting the same load tests with literally the same 24" bushmaster as mine and had zero issues. I've noticed before that my brass has had some decent gouges like it's under pressure when the cam rotates but thought it was just needing to be broke in. Now it's all making sense.
Any suggestions? I think this is actually a gun issue and not the loads themselves. I've got a few ideas to try but wanted to know if anyone has run into this issue before.
Gun Profile:
Bushmater 24" fluted free float barrel.
Bought at gun show with approx 200 rounds through it (condition appeared to confirm this.)
Ran 300 rounds through it before blown primers
Full length buttstock
Rifle buffer
