The L-N-L Headspace Gauge is the best method we’ve found to extend brass life, improve accuracy, and enhance safety. The gauge measures variations inyour brass before and after firing or re-sizing. It allows for comparison between fire-formed brass from your gun and your re-sized brass. Any of five interchangeable bushings are attached to your caliper using the same body as foundon our Bullet Comparator.
The five bushings that come with the L-N-L 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. See chart provided or consult product instructions for cartridge/bushing size details. Dial Caliper sold separately.
