How Lock-N-Load® Works

The Hornady® Lock-N-Load® System is as Easy as 1-2-3
Insert the Lock-N-Load® die bushing into the press bushing and lock it into place with a twist. The six locking lugs on the die and press bushings will hold it securely in position.
Insert your standard die with 7/8"-14 threads into the Lock-N-Load® bushing.
Adjust the die to the proper position and lock your setting into the place with Hornady's unique Sure-Loc lock ring.

To change calibers, simply twist the die counterclockwise, remove die and insert your next preset Lock-N-Load® die and bushing. Because they remain locked in their Lock-N-Load® bushings, your dies will remain exactly as you set them. The positive locking action of the Lock-N-Load® bushings holds the dies in rock solid, perfect alignment.

Once you try Lock-N-Load® from Hornady®, you'll NEVER want to go back to your old system!
