Trying to work out how I did this.
.308 brass that's been reloaded 3 or 4 times, loaded 100 rounds all fine except two which have crumpled evenly down, not just a dent on the side. Like the shoulder was pushed down by a ring. 1 about a mm, the other is about 2mm.
I sized and primed them all first and didn't notice a problem and with the way they've gone down it's like the tension of the bullet in the next was too much and has squashed it down.
I didn't expect to be able to do that in seating a bullet though, I thought it would only be during sizing the brass.
Anyone?
