Every gunsmith understands that the precise utilization of a chamber gauge is the most reliable method to accurately verify the chamber length of a rifle. Proper chamber measurement is critical in metallic and semimetallic reloading processes, ensuring both safety and optimal ballistic performance.
The chamber space refers to the exact distance between the chamber face and the base of the cartridge when the action is fully closed. Excessive chamber space can pose significant safety hazards, including increased risk of case rupture, and can severely degrade the rifles accuracy and consistency during firing.
When a rifle action closes on a GO gauge, it confirms that the chamber will safely accept any ammunition manufactured within the stringent SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, which serve as the industry standard for cartridge dimensions and pressures. This ensures that reloaded or factory ammunition will chamber correctly without undue stress or deformation.
Conversely, if the rifle closes on a NOGO gauge, this indicates that the chamber may have excessive headspace. Excessive headspace can lead to dangerous conditions such as case stretching, primer flow, and potential catastrophic failure during firing. Most experienced gunsmiths aim to maintain the chamber headspace between the GO and NOGO gauge dimensions to balance safety and performance.
Finally, if the rifle closes on a FIELD gauge, it signifies that the chamber headspace is dangerously close to or has exceeded the maximum allowable chamber size as specified by SAAMI. Operating a rifle with such excessive chamber space is highly unsafe and can result in severe damage to the firearm and injury to the shooter.
In summary, the meticulous measurement of chamber space using GO, NOGO, and FIELD gauges is an indispensable practice in precision rifle maintenance, metallic and semimetallic cartridge reloading, and ensuring the longevity and reliability of hunting and tactical firearms.
