I picked up a box of 50 Federal .45 ACP +P awhile ago (P45HST1) and noticed some inconsistencies in the ammo. A few of them seem to have a heavy roll crimp mid way between the cannelure and the top of the case. I've never seen this in .45 ACP. The pics will explain it better. The normal one measures at .471" and the abnormal at .464" The bullet on the left is the worst one of the bunch. The right bullet is how the majority of the box is. Again, without the flash to show definition. Normal?
