.....and I don't know why! I'm using Lee Carbide Dies with brand new Remington brass and Remington 185 gr JHP's. I think I've flared the mouth as much as I can, and stil the edge of the cases are collapsing.
Any clues as to what I might be doing wrong?
This is a "used" Die set that I'm using for the first time, could it be the culprit? I just finished loading 250 rounds of 9mm with a "new" die set and no problems. Any help would be greatly appreciated. Thanks!!
Knee deep in brass, still shootin fast!
