I must be missing something and can't figure it out. I loaded about 300 rds. of .223 on my Dillon 1050 (my first reloads), (I know, should have checked a few of the first ones, ROOKIE MISTAKE) and they won't chamber in any of my AR's, actually get stuck in the chamber. I checked everything I know to check, even compared them to factory loads, that work fine and they are identical. They check out on the case gauge, O.A.L., Checked every measurement with my calipers. I've must have missed something. If you're near Midland and wouldn't mind stopping by for some pointers, I would appreciate it.
