Good point about the shoulders Jim. I wager thats what sarge was talking about with his #1.
Oh, I'm not referring to the little dents from excessive lube..... I'm talking about buckled shoulders.... buckled like bullet crimped before seated fully ....
Getting the seating depth just right and then having to futz with it to get the die to crimp and yet keep the same seating depth...... the thin case is unforgiving.
