Lock‑N‑Load® Headspace Comparator & Anvil Base Kit
Lock-N-Load® Headspace Comparator
The Lock-N-Load® Headspace Comparator extends brass life, improves accuracy, and enhances safety. The gauge measures variations in brass before and after firing or re-sizing. It allows for headspace comparison between fire-formed brass and re-sized brass.
The five bushings that come with the Lock-N-Load® Headspace Comparator provide the ability to check most bottleneck cases, from .17 Rem through belted magnums. Ackley Improved chambers use the same bushing size as the parent case. See chart provided or consult product instructions for cartridge/bushing size details.

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.
