In this pict there is a circular abrasion ring right through the "WIN and REM" words. I am guessing it's a bolt head issue. I am wondering if anyone has any comments on the Pacific Tool bolt head replacement?
I think it could be low pressure, I am loading about mid range for a 55 grn with 33.6 grn of Varget.
Is the linear bullet tracking do to the heat of my barrel, or do I need to learn how to hold the damn thing still?
