Hi all, I'm new to boolit casting. I'm starting out casting with a Lee C430-310-RF mould to cast boolits for my 444 Marlin rifle. I'm FINALLY getting good boolits out of my mould, long story there. I plan to use Hornady .44 cal gas checks. These gas checks slip onto the base of the boolit with no interference, they are loose on the base. If I understand the process, the gas check would be crimped onto the boolit as part of the sizing operation?? I DO have a Lee sizer for this caliber. The boolits are dropping from my mould at about .432" diameter which is about perfect for my 444 Marlin. Since the size is right out of the mould, I do NOT want to size my boolits.
How do I crimp the gas checks on the base of the boolit if I'm not sizing the boolit???
I thought about using my Lee factory crimp die but I don't think the collet will squeeze small enough. I've searched this forum for an answer but I have not come up with a satisfactory answer. I'd rather not use glue or Locktite to glue the gas checks onto the boolit, I'd rather find some way to crimp them if possible. Does anyone make a crimp tool for crimping gas checks? Thanks.
