As I said in the other thread I have going, I'm loading 9mm Luger in a dillon 550, using Lee dies. Sporadically, but fairly regularly, I get a crushed/rolled edge of the casing during the expansion/powder charging stage. It's usually about 1/4 or less of the rim is folded in on itself.
This is obviously the Dillon die, since that stage is proprietary on Dillon machines. I looked in the die and at the funnel, and there doesn't appear to be any dirt or other nasties in there that might catch and push the rim in, at least to my eye.
I called Dillon and the said to try loosening the locknut on the die, then raising a case into the die and tightening it then. That would adjust the die a bit better and make things line up better. I tried that, to no avail.
I am putting a sizable flare on rim. I know its not ideal, but I've been too lazy to adjust the dies (it's a pita to adjust the flare on the Dillon). Could the cartridge be pushed up too far and possibly catching on something within the die? This seems unlikely though, as why would it only happen sporadically? Unless it is just an issue of different lengthed cases?
