Lyman MSR Multi-Caliber Ammo Checker Cartridge Gauge


Lyman's Ammo Checkers check the quality and consistency 
of both reloaded rounds and purchased ammo. 

A must for any auto shooter for easy and consistent feed. 

You can't afford misfeeds, so get the easiest "no-go" gauge available today! 

These Ammo Checkers are gauges that allow a reloader to 
quickly confirm that their ammunition will fit in their chamber. 

Machined from solid blocks of 6061 T6 aircraft grade aluminum and 
cut with custom tooling to SAAMI minimum chamber dimensions. 

One gauge will work with a variety of calibers. 

Just drop your loaded rounds into the ammo checker,
 and if the round fits into the gauge, it will fit in the gun's chamber. 

Each caliber is clearly engraved on the gauge.

223 Remington
300 AAC Blackout (7.62x35mm)
450 Bushmaster
