The Lock-N-Load bushing system will forever change the way you switch from one caliber to another.  Lock-N-Load technology allows you to stop loading, change dies and start loading another caliber in a matter of seconds.  

Simply thread your die (7/8"-14 thread) into the Lock-N-Load Die Bushing (male) and insert the assembly into the press bushing (female).  Twist it clockwise to lock it in a solid, perfectly-aligned position.  Then adjust your die as usual and tighten the lock ring.  Remove by twisting reverse 1/6 turn.  The die assembly comes out and the next die assembly can go in.
