I have hundreds of spent brass from a 722 Rem that I am considering using as the basis for a custom rifle. In examining the brass, I noticed that the firing pin is not hitting in the center of the primer. Is this something that should be addressed when the action is being "trued" etc? How can you center the firing pin without using a larger diameter pin? Im mostly asking because I have lots of interest but zero experience with the precision machining aspect of gunsmithing.
