Precision headspace comparator that extends brass life and improves accuracy. Measures brass variations before and after firing or resizing. Includes body with five bushings for .17 Rem through belted magnum cases.
The Lock-N-Load Headspace Comparator is an essential tool for serious reloaders who demand precision and consistency. This gauge allows you to measure variations in your brass before and after firing or resizing, giving you the data you need to make informed decisions about case life and chamber fit.
The kit includes the comparator body and five interchangeable bushings, allowing you to check headspace on cartridges ranging from .17 Remington through belted magnums. For Ackley Improved chambers, simply use the bushing size that matches the parent case.
The comparator measures the distance from the case shoulder to a reference point, allowing you to compare fire-formed brass against resized brass. This data helps you optimize your reloading process and maximize the lifespan of your brass.
Consult the included chart or product instructions to identify the correct bushing size for your specific cartridge.
