I am having a problem loading 380s. I have a Lee Turret with a Lee 4 die set. I am damaging the mouth of case when I am putting the flare and powder in the case. The damage is a nick about 1/8" wide and 1/16" deep on the edge of the mouth. I have remounted the dies, indexed over one hole on the turret (in case I had a bad base), and have backed out the die to the point that the powder won't feed and it still does it. All the other calibers (9 , 40 and 45) work fine. 380 brass is too hard to find without tearing it up after you get it. Any suggestions?
