For Sale - Custom made .30M1 Carbine Case Gauges

These Case Gauges are a "go/no-go" gauge for a loaded round. Or in other words, if a loaded round drops all the way into the Case Gauge, it will fit in your rifle or handgun's chamber.

Always use a case gauge when reloading any rifle caliber because it is important to "know" that your headspace is being set correctly.  This process shows if your rifle ammunition is being produced within industry specifications.

The overall length of the cartridge case must be closely monitored, as an overlong case (due to stretching from repeated firings or a new case that is out of specification) can keep the cartridge from fully seating in the chamber.  A cartridge case stuck in the chamber and preventing the bolt from completely closing and locking is asking for trouble. A long or broken firing pin stuck in the forward position coupled with an overlong case, could result in the rifle "firing out of battery" causing a ruptured cartridge case and possibly injuring the shooter with brass fragments or escaping gas.
