I came across an old 222 Rem sizing die, of unknown make, that was pretty soft steel. I decided to make a bushing type sizing die out of it that would work in a press.
I bored it out and inside threaded it in the lathe, then I turned and threaded a plug to hold the bushings in place. I then turned and bored bushing to various sizes. It works very well.
