These are Borden BRMXD. CCI - 200 Primer, never noticed any losse pockets and I bump shoulder to 2-3 thou and check nearly every one as I size. This is why I am confused as both bolts have that little half moon rough edge.. albeit magnified and hard to see with the naked eye. I’ve read about gas cutting therefor posted this to determine from you experts if I’ve got a problem. I am going to seat some primers in my 8x fired brass that I retired ( for no good reason really) and compare the presuure to my 2 x fired brass. I just hope I’m not seeing something that will get worse….
Even the Army would have condemned and replaced that M16 bolt.Right Savage Azis 223 normal.
Left Remington 600 in 243. Blow out from defective primers.
Both shoot ok.![]()
Even my M16 kept running with this bolt face.![]()
The round count has a lot to do with it. More rounds fired, more noticeable.
I worry about other things.
