Sevens, that was in fact a Federal SP primer. I hate those primers. I figured to use them in this load because I was sure it would be a low pressure load. I was just curious if a low pressure load could flatten primers. Thinking maybe brass not expanding enough to seal in chamber therefore letting brass travel back harder flattening the primer. I use WSP primers when loading higher pressure loads. I load 6 grains of Unique with a 85 grn XTP with no signs of pressure. That's a pretty accurate, low recoil load. That's what is in the 327 when it's pulling CCW duty.
