I have a few rifles with MUCH worse looking bolts.

I'm the owner of this particular rifle. The loads that caused the primer pinholes were 30.5 and 28 grains of Varget pushing 139 grain FMJ. The primers are winchester brand Large rifle primers. This problem only occured a couple of times out of around 40 rounds total.
