Neck sizing and cast bullets
I use the Lee Collet neck-sizing die--works slick, accurate ammo, no lube to have to clean off. It includes a decapper, and since there is no expander ball, there is never a problem with the non-lubed case neck, inside or out.
Cast rifle bullets--The fans of cast rifle bullets will claim superb accuracy from them. Real blackpowder accuracy nuts actually use a 2-part bullet cast from 2 different alloys. And a paper patch wound onto the bullet. But they do get results. You shoot cast bullets slower than jacketed rifle bullets, and the reloading recipies are all different. Gas checks are just about mandatory in rifle loads, I understand. Lead bullet pistol loads up to about 1300 fps can be done w/o the gas checks.
