• FASTEST WAY TO GAUGE AMMO - Easy to spot bad rounds
• DESIGNED TO WORK WITH 100 ROUND AMMO BOXES - Once you load the gauge, flip your rounds right into the box with no more handling and head to the range!
• CNC MACHINED AND REAMED WITH SAAMI SPEC CHAMBER REAMERS
• MADE IN USA
 
Supermatch gauges are made to smaller dimensions than our regular match-grade gauges, so they will reject more ammunition to ensure any that does pass will fit even the tightest SAAMI-spec chambers.
 
The Large Chamber gauges are reamed larger than our standard match gauges and designed for large-chambered pistols where a regular gauge rejects too much ammunition.
