If left alone, and no more primers pinhole, what will happen? I had 3 winchester primers pinhole out of 30 243 shells I loaded at one time. After reading this thread, I looked at the boltface. Sure enough, there are 3 tiny pits around where the edge of the primer sits. They don't look like much, should I take it to a gunsmith or something, or just shoot it and keep an eye on it. I already have some CCI primers. I put the winchesters at the back of the shelf. Are they good for anything now (low pressure loads or something) or should I throw them away?
WIWD. Red flag the Win primers to be used only under hopeless desperation measures.
Advice from several gunsmiths and very experienced HP shooters at my club is that the bolt face pitting is cosmetic.
If you want to fix it, Do as Shrapnel suggest and have a
very shallow groove milled to clean up the pitting. Alternatively, send the bolt to Gre-Tan to have the bolt face bushed.
