I'm trying to seat PB checks (aluminum) on a Lee TL410-210-swc. They're cast with acww, and come out of the mould at .411-412". I tl them and size them to .410 in a Lee push through die. I've eased the entry into the die with a cone shaped stone turned in a drill press. I push them base first into the die after pushing the check onto the base of the boolit. The problem is no matter what I use for lube the check ends up "smeared" half way up the boolit. Is there any hope for correcting this?
