I know this has been asked before and the usual answer is "buy a swaging press". But, before anyone jumps on that band wagon...
I am ONLY interested in swaging 22LR brass casings for use in .224 projectiles. It would be for a low volume amount, almost like "I am not dependent on the manufacture". Most other calibers have the ability to shoot plain cast or gas checked cast boolits. I would have the dies made by a buddy of mine (40+ years tool and die experience) and a full machine shop. If I can get a sketch of the part, he can make it. Has anyone done such a thing in the past?
I was thinking of having a mold blank drilled/milled to the correct diameter and depth to make the lead cores.
Any help in the feasibility and ability of sketch/dimensional availability would be greatly appreciated.
