Fired primer damage question......

Nephew -- experienced reloader, and every weekend tactical shooter -- inherited a very nice high condition Arisaka Carbine. I was picked out of a Japanese Armory in Tokyo by a relative and other than a ground Mum. We spent an afternoon doing a cleaning, and shiney bore, every thing fits and matches. He tried it out with the US commercial ammo that came with it: shoots bullets in groups

Sooo, as he is already a loader...he picked up dies, powder, bullets, etc and made some ammo...Took it too range, and an anomaly developed. At what appeared to be random occurrence, an ejected case would have a smeared primer strike, and a pin-hole 'burn-thru' on the edge of the primer.

No idea, other than unsubstantiated guesses -- so toss this out to The Assembled, in the hopes that it;s one of those "Oh, yeah....it one of THOSE things." Thanks for a lookover.
