Years Ago my Dad produced and sold bullet molds ...

They were for his "Slip-In" practice bullets.. full wadcutter, light for the caliber, intended for short-range and aerial practice shooting.

Designed almost like a heel bullet, once your cases were fired in your sixgun you never needed to size or crimp them. The reloading sequence was simply: deprime ... prime .. add powder .. seat the bullet by thumb pressure and then shoot it.

Case life was indefinite since there was no sizing, neck expanding or crimping. He had one .44 Special case he had logged over 1200 shots with.

Cleaning out the safe I ran across a couple of his "Pocket Reloading Kits." All you need to add to these is a punch to deprime, a pair of pliers to hold the mold while casting, and a powder scoop of the correct size for the caliber.
