This 5-pack of Hornady Lock-N-Load Headspace Comparator bushings (brand part no. HK55) extends brass life, improves accuracy, and enhances safety by letting reloaders measure variations in brass before and after firing or resizing. The gauge allows a direct headspace comparison between fire-formed brass and resized brass, so handloaders can see exactly how far they are sizing the shoulder back. The five included bushings cover most bottleneck cases from .17 Remington through belted magnums, and Ackley Improved chambers use the same bushing size as their parent case.
