Hornady Lock-N-Load Cartridge Gauge 30-06 SPRG

The Hornady 30-06 Springfield Cartridge Gauge allows users to check their cases and loaded ammunition to ensure a correct fit in SAAMI chambers. Simply Slide your sized cases or loaded ammunition into the case gauge. If it sits flush your case is in spec. If the neck or base of the case protrudes your cartridge may need further sizing or is unusable.
