federal quality standards, or uplula damage?
I bought 200 rounds of 40S&W Federal 180 gr HST HP from ammunitiontogo.com recently, and today I noticed that many (~2/3rds) cartridges from the box I was loading from had ridges in them; some very deep, some only slight.
I checked the other boxes that have not been opened, all 4 boxes have the same lot number, but only the ones that have been loaded into magazine have the ridges; a sampling form the other 3 boxes revealed no defects at all, aside from a 1 or 2 that had some very thin, small dings.
Here are 2 cartridges representing the worse defect and least worst defect. Out of the box of 50, approximately 30 of them have ridges such as these.
In some cases the dent goes all the way around the circumference of the casing, but in most cases, it's only about a ~60 degree arc across the case.
Could the uplula loader be causing this?...they've only been loaded into mags maybe twice, and only 1 round here and there has been fully cycled through the gun.
It'd be easy to blame Federal, except that it's only one box out of 4 that have any problems such as this and they're all from the same lot....perhaps this box was on the beginning or tail end of the lot?
Should I just shoot them and get rid of them, or should I send them back?
