I expect primer crimps in 9mm, 5.7, and .223 so I take care of those before they get close to being loaded. But the other day I was loading some .40 S&W. I had no <deleted> clue that any .40 brass had primer crimps. At first I thought I was just running into brass with tight primer pockets, like S&B, but nope!! Ran into a bunch of WIN headstamps with crimped pockets. WINCHESTER headstamp didn't have crimps though. Also a few other random pieces of .40 with crimps, it was nickel plated stuff but I don't remember the headstamp, just remember it was a common brand.
