A few months back I bought a box of 50 Federal HST .45 ACP +P (P45HST1). As I loaded up a new mag today I noticed something odd about a few rounds. I've never seen anything like this with other 45's. I haven't been reloading long but this just doesn't look right. There seems to be a super heavy roll crimp half way between the cannelure and the top of the case. This pics will show this better. A normal cases measures .471" while the weird ones are .464" a pretty big difference.
The left bullet is the weird one.
Here's another pic without flash to show definition. You can barely make out the ring on the right one.
I did a thorough inspection and: I initially shot 5, 11 were really bad while the remaining 34 varied from slight to almost normal. On closer inspection all had that weird ring around them to some degree. The 5 I shot fired fine and felt like +P ammo should. I should also note the box is labeled "Federal Premium Law Enforcement Ammunition." I thought the LE stuff went through an even tougher inspection??
This can't be normal??
