I turn my own custom diameter push-through dies. A foot long piece of 7/8-14 all-thread is good for a half dozen dies. I don't care for Lee Liquid Alox so I pan lube the oddballs and then push them through a die. Doesn't have to be hardened - a soft steel die will last forever.
Yeah, I've been thinking about making the next one too. Probably make a .358" one.
