This single stage press features our exclusive Lock-N-Load technology in the ram, which means you can change your shell holder over to ram-prime, then move the shell holder to the top plate. Once the holder and ram-prime are set, they stay that way. A quick change to a Lock-N-Load bushing makes switching over from ram-prime to die use faster, too. The Kit Includes: Hornady 50 BMG Reloading Press Hornady 50 BMG Reloading Die Set 50 BMG Shell Holder 1½"x12 Conversion Bushing Mfg: Hornady
