Pistol primers and breech block damage?

[Kenny Wasserburger]

Many of the original Sharps Rifles had a bushed firing pin hole as a repair for a cratered firing pin hole.

It’s common enough, if you’re the original owner Shiloh will replace the block under warranty. I believe with nearly 20,000 rounds on the old hell bitch rifle it’s on the 3rd breach block now.

My 40-70 is on its second block yet it was originally a 45-70 with 10,000 rounds on that barrel and over 6000 on this barrel.

Ps pistol primers if not headspaced in some manner will certainly do this as they are shorter then the large rifle primer.
