I have not done the process personally, but a friend of mine makes 22 caliber bullets from spent 22 cases. I have shot some of them and they worked good. It's a bit labor intensive and takes quite a few bullets to break even on the initial investment. Kind of neat to see the 22 headstamp on the bottom of the bullet.
If the idiots have thier way with the ammo accountibility, the press will be collecting dust.
