Here's my situation...
I shoot a Springfield 1911-A1 and have never had a problem with factory ammo. I recently decided to start reloading with 230gr LRN from Oregon Trail with 5gr of Bullseye as this seems to be very popular in other threads. I am using Lee factory dies and have been reloading for a while now. I am delighted with the improved accuracy but the issue I am having is my slide locking back after the 6th round. It appears to be locking back as if I had only 6 rounds in the magazine. I only use factory mags and the problem is not specific to any one magazine. I have tried setting my OAL at various places from 1.250 up to 1.275. Between 1.265 and 1.270 seem to be best but it is still happening on every other mag.
When the slide does not lock back as mentioned above, it will strip the 7th round but the slide will not travel forward completely. It acts like the bullet does not fit. I drop each round into the barrel when reloading to check the fit as I am new to 45ACP. I can reload these "problematic 7th rounds" into a mag and they fire fine. I hope someone can help!! BTW I am new to THR and I love this site...always good info.
