I'm using a Lee Profile crimp die for 10mm, and I have a recurring problem. When I screw the die in enough to crimp the mouth properly, it's hard to pull the ram back down (pull the case out of the die). It seems to get stuck, not at the top where its actually doing the crimping, but basically where the case mouth is passing the carbide ring on its way out. If I don't crimp them like this, and back off just a bit, the sticking problem doesn't happen, but the cartridge isn't reliable in my Bar-Sto barrel.

Any ideas of what I'm doing wrong?
