This might be a long shot, but can’t hurt to ask. I’m attempting to modify one of my fired cases by drilling out the primer pocket and tapping with 3/16 x 36 threads. The goal is to use this case to measure against while sizing my brass. This way I would be able to consistently measure when setting up my sizing die so that I bumping the shoulders down by .002”. As far as I can tell using a fired case is the only way to do this, so purchasing a Hornady modified case isn’t very helpful in this case.
I can’t find a way to fixture the brass so that I can drill the necessary hole (bit size L) without deforming the case. If anyone has suggestions, I am eager to try. My thought is chucking up in a lathe, equal pressure could be applied to the case outer surface such that minimal deformation occurs.
Anyone have similar experience? If so, what did you do? I also wouldn’t mind paying a member who is close that has access to a lathe. I have the drill but and tap already.
