Headspace No-Go Gauge
FOR: 8X57 Mauser (.323 Diameter)
HG8X57N
NEW!!
Forster Products manufactures precision headspace gauges to maximize safety and accuracy in your rifle.
These gauges are necessary when finish chambering a barrel, or when checking the chamber of a used gun to be sure the headspace dimensions are within safe limits.
Machined from A2 tool steel, these gauges are held to tolerances within 0.00015" to ensure accurate testing of your rifle's chamber.
Notes:
Headspace standards are set by SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications.
Headspace is measured from the bolt face to one of four locations, depending on the cartridge used.
The measurement is taken from the rim of rimmed cases like the .30-30, or the shoulder of a necked case like the .30-06, the case mouth of a straight or tapered case like the 30 Carbine, or the belt of a belted case like the .300 Winchester Magnum.
No-Go Gauge:
No-Go Gauges are sized to the maximum recommended headspace dimensions (Not a SAAMI maximum measurement).
If a rifle will chamber the no-go gauge, it may still be within specifications, or this could indicate excessive headspace.
To determine if the rifle is safe to shoot, the chamber must be checked with the field gauge
