I finally got some .223 reloaded and I cycled some through my AR by hand just to make sure the OAL was ok. When I did the BCG seemed like it was sticking on something and it was somewhat difficult to pull back and eject the round by hand. I cant figure out what could be causing the issue. The brass is mostly once fired PMC with a few other here and there. All the brass in trimmed to the proper length and deburred. The bullets are 55 gr. Hornady FMJ BT's. OAL is 2.24 which is in between what my Lymans and my Hogdon says. My gun is fairly clean and well lubed. The cases were lubed with Hornady One Shot, but they weren't tumbled. Haven't gotten one yet, due to the expense. So does anybody have any ideas? I am going to try to find some factory ammo laying around to see if I'm having the same issues with that.
