First of all let me start with my reloading troubles with my lone wolf barrel. I am using a lee resizing die sizing all the way down. I am using 180 gr tc moly coated bullets. The issue that I am having is that 10 percent of the rounds that I make are not headspacing correctly. they actually headspace ont he lead in front of the cartridge mouth. I have taken all the measurements on a bullet that falls freely into the barrel and those that don't and I can't find any differences. I have tried more crimp, less crimp, glock barrel, LW Barrel. All give the same result basically. the best I can get out of changing all of those is 90 percent reliability. I did have a friend who has been reloading for years tell me that I would be ok dropping my OAL a bit as long as I am not approaching max pressure. I am on the very bottom end right now (4.7 gr wsf to 1.125 OAL) The problem is that if I want to make major withthat round I am going to have to up that to approximately 5.6 gr of WSF. The question is that if I up the charge to make major AND reduce the OAL to 1.115 to make them feed reliably, SHOOTING a GLOCK, am I going to have a KABOOM?
