The Hornady Lock-N-Load Headspace Gauge extends brass life improves accuracy and enhances safety. Any of the five interchangeable bushings attached to your caliper uses the same body as found on the Hornady Bullet Comparator. The five bushings that come with the Lock-N-Load Headspace Gauge provide the ability to check most bottleneck cases from .17 Rem through the belted magnums. Ackley Improved chambers use the same bushing size as the parent case.
The Hornady Lock-N-Load Headspace Gauge kit stands out as a top contender if you're looking for a comprehensive headspace gauge kit.
