Looking for Help here.... I have been reloading ammo for yesrs on a RL550 with no problem in all sorts of calibers; .45acp, .223, 9mm etc... Just decided to handload for my wifes M&P40 so I got some componets ( once fired fed brass, CCI primers, Win 231 and 165 gr JFP's) and loaded 20 or 30 to go test. Well the chamber would not fully close on about half of them and the ones that did chamber I caught hell trying to get the slide to unloack and cycle. I check my OAL and its within the limits according to Lymans 47th and Lee loading manuals. In lymans it did mention something about not reloading for Glocks and simular pistols with unsupported chambers. Im a 1911 shooter for life but wanted to try something different and cant figure it out. I am guessing it is something to do with the case sizing stage but just not sure. Looking for the infinate knowlege of THR......What and I doing wrong here guys?
