primer piercing?

G.T. · 11-15-2017, 09:08 PM

Hello to all, I have recently been working on a Luger that has a unique issue... It runs perfectly on 115 gr. WW box target loads, but on 115 gr. S&B ball ammo, it works great, but it pierces the primer almost every time? It shows up readily as a black hole and cannot be missed?... Now, the barrel does/or has, had/or have, an issue with a very thin ridge for the case mouth to headspace on, (corrected with a chamber reamer) but the cartridges measure out identically? And, the chamber is correct to close on the -GO- , but not on the -NO GO- ?? Does anyone know the correct firing pin protrusion dimension?.... Back to the range tomorrow.... with some sample guns that are as of yet, without issue?... Best to all, til....lat'r.....GT
