Every gunsmith understands that the precise utilization of a chamber gauge is the most reliable method to verify the chamber length of a rifle. Accurate chamber measurement is critical in metallic and semi-metallic cartridge reloading to ensure optimal ballistic performance and safety.
The chamber space refers to the distance between the chamber face and the base of the cartridge when the action is fully closed. Excessive chamber space can lead to dangerous pressure spikes and negatively impact shot consistency and overall accuracy, which are paramount in precision shooting and hunting applications.
When a rifle action closes on a GO gauge, it confirms that the chamber will safely accept any ammunition manufactured within the SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) industry specifications. This ensures that the cartridge will properly headspace, maintaining safe pressure levels and reliable ignition.
Conversely, if the action closes on a NOGO gauge, it indicates that the chamber may have excessive headspace. This condition can cause case stretching, premature brass fatigue, and potential case rupture, all of which compromise both shooter safety and firearm longevity. Most professional gunsmiths aim to set the chamber dimensions between the GO and NOGO gauges to balance reliability and safety.
Finally, if the rifle closes on a FIELD gauge, the chamber is dangerously close to or has already exceeded the maximum chamber size allowed by SAAMI standards. This situation poses a significant risk of catastrophic failure, including case separation and increased chamber pressures, which can result in firearm damage and personal injury.
In summary, meticulous chamber measurement using GO, NOGO, and FIELD gauges is an essential practice in the maintenance and reloading process for metallic and semi-metallic cartridges. It ensures that each round is fired under optimal conditions, maximizing accuracy, safety, and the overall performance of the rifle.
