This affordable headspace gauge from Hornady allows the handloader to measure changes to the headspace of cartridges with a dial/digital caliper. Different bushing sizes (depending on cartridge family) insert into the Hornady Lock-N-Load Comparator Body (not included), which attaches to a caliper. This handloader can then measure the changes between fired and sized brass. this enables the handloader to adjust his sizing dies for a proper fit in his chamber. When a handloader oversizes his cases it can cause excessive headspace problems, one of which is to shorten the life of the brass. The Hornady Lock-N-Load Headspace Gauge will allow the user to measure brass from the case head to the datum line on the case shoulder.   The bushing is sold without the Comparator Body.

Hornady Comparator Body B2000, is sold separately and we can bundle it for you for reduced shipping.
