Hello need some help from you knowledgeable individuals. Hope I’m posting this in the right section. I am reloading .45acp for my Springfield 1911 and I have done quite a bit of troubleshooting myself. I am using the Lee 6 cavity mold and sizing die. For reloading the cases I am using the Lee 3 die set (sizing die, powder through expanding die and bullet/crimp die). I loaded the rounds to .265, feeding the rounds from the mag they are going most of the way in the chamber but the slide is staying back about 1/4 inch and I have to “jimmy” the slide to extract it. If I place the round in the chamber by hand and drop the slide it will chamber properly and fire. If I only have 1 round in the magazine and drop the slide it will also chamber most of the time. I proceed to load them all the way down to .120. At this point if I have more than 3 in the mag they will not feed from the magazine. Factory FMJ bullets with the same ogive feed fine no matter what. What’s going on here?
