I got into reloading because I bought an "obsolete" Savage Model 340, 22 Hornet back around 1979. Ammo, when you could find it, was sky high. Reloading has been a passion ever since.
Maybe this oversized cylinder is The Universes' way of telling you to start casting boolits. You should be able pick up used equipment from The Cast Bullet Assn forum webite, or The Cast Boolits website for cheap.
