Hornady Lock & Load Headspace Comparator Kit

The Hornady Lock ‘n’ load headspace gauge is the best method to extend brass life, improve accuracy & enhance safety. The gauge measures variations in brass before & after firing or re-sizing. It allows for head space comparison between fire-formed brass & your re-sized brass. Any of the five interchangeable bushings are attached to your caliper using the same body as found on our bullet comparator.

Comparator body and 5 bullet inserts for bullet diameters: .330″, .350″, .375″, .400″ & .420″
