Just wondering what everyones experience with the quality and uniformity of the roll crimp given by the Lee Seating Die has been like. On my .38 spl die, it doesn't really roll the case lip in, but rather just seems to bottle neck it down (even with a very very light crimp). It will only squash it on a little bit, and then for the rest of the case roll it in. Am I just overcrimping here, and needing to back the die out a fraction of a turn? I was kind of expecing to see a distinct roll in the crimp, but it seems to go from very very light roll (I mean very light), to bottlenecking the case. Is this right?
