If you cast your own bullets, Hornady’s crimp-on gas checks will enhance their performance. During sizing, the gas check crimps to the base of cast lead bullets to seal gasses and protect the base from deformation. Hornady gas checks are the only real choice for bullet casters. Packaged 1000 per box.
