I just stopped using GM205M Primers in the AR.
Do to Peircing, I have had a few in the last couple hundred rounds.
Also quit using WSR Primers for the same reason.
Switched to Rem. 7 1/2, hope these work better.
yep, same on both the gold colored WSR's and the federal match. The fed match flattened at the much earlier stages in the work up. The WSR's bit me when I brainfarted and used up my silver WSR's and switched to the gold colored without reworking. That cost me a firing pin tip. Loads were below maximum.
I now use the rem as standard and the Wolf for plinking. My remainder of my 2k of gold WSR's are used in my bolt rifle .223 shooting.
