Product Description

The Hornady Lock-N-Load Headspace Comparator helps you measure and compare case headspace before and after firing or resizing to support consistent brass setup, improved accuracy potential, extended brass life, and safer resizing practices. This kit includes a comparator body and five interchangeable bushings designed to cover most bottleneck rifle cartridges from .17 Remington through large belted magnums. Bushings mount to the comparator body and attach to calipers, allowing you to measure from the case head to the datum line on the case shoulder for repeatable headspace comparisons. Ackley Improved chambers use the same bushing size as the parent case.

Product Highlights

  • Measures case headspace changes before/after firing or resizing for consistent chamber fit
  • Includes comparator body plus five interchangeable bushings for broad bottleneck cartridge coverage
  • Supports brass life extension and accuracy-focused resizing by enabling precise comparisons
  • Bushings fit the comparator body and attach to calipers via thumb screw (calipers required)
  • Compatible guidance: Ackley Improved chambers use the same bushing size as the parent case
