Swaging lead bullets to take a gascheck has been a difficult project for me, can't seem to get the knack for doing it right.
I succeeded in reaming an ejector stem base to form a rather snug but not real tight fit. Wanted them to fit tighter like a regular gascheck bullet mould turns them out.
Consequently the gaschecks will sometimes fall off or stay in the lubesizer press when trying to seat them tighter.
Another thing is the extremely thin walls the reaming left on the ejector stem. This setup doesn't look like it will last very long as its fragillity of thin wall metal.
Perhaps I need another approach, maybe a bigger die punch set up...but how?
I'm ready to accept any suggestions if someone has been there done that.
Is it going to be OK to seat the gascheck in a non tight form on the cast lead bullet, has anyone done this practice of just placing the gascheck on the base of the bullet loosely and seat and crimp it in the brass case.
I'm experimenting with .44 caliber right now.
