Forster .257 Roberts GO Headspace Gage
Precision headspace gage for .257 Roberts rifles. Forster's GO gage ensures your chamber accepts standard ammunition safely and accurately. Essential tool for gunsmithing and rifle maintenance.
Understanding Headspace
Headspace—the distance between your rifle's breech face and the cartridge base when the action closes—is critical to both safety and accuracy. Excessive headspace can lead to dangerous brass rupture, allowing high-pressure gases to escape rearward. This is why precise headspace measurement matters.
The Forster Advantage
Forster manufactures headspace gages with exacting standards and meticulous care. Each gage is engineered to provide accurate, reliable chamber testing that you can trust with your safety.
How It Works
GO Gage: If your rifle closes on the GO gage, your chamber accepts all ammunition manufactured to SAAMI (industry standard) specifications. This is your baseline for a properly functioning rifle.
NOGO Gage (sold separately): If your rifle closes on a NOGO gage, your chamber may have excessive headspace and requires gunsmith evaluation.
FIELD Gage (sold separately): If your rifle closes on a FIELD gage, your chamber is dangerously close to or exceeds SAAMI maximum specifications and should not be fired.
Professional Standard
Most gunsmiths chamber rifles with headspace between GO and NOGO dimensions. This gage is an essential tool for gunsmiths, reloaders, and serious shooters who demand precision and safety.
