It looks like my M1917 has just a bit of excessive headspace as evidenced by protruding primers and excessive case stretching rings using full power loads. If I use reduced loads, this seems to not be an issue. My question is there a way to adjust your die to resize your case to accommodate for this longer chamber? Or after you have fire formed the cases, then would neck sizing only be best because the case is now a fit for the chamber? It seems the headspace is not TOO excessive that it needs gunsmith work but want to hear what you experienced folks and maybe some gunsmiths have to say. Thanks in advance.
