Forster Headspace Gage FOR 350 LEGEND GO

The Forster Headspace Gage FOR 350 LEGEND GO is the precision measurement tool every gunsmith and reloader needs to safely verify chamber dimensions. Proper headspace control is the foundation of safe ammunition reloading and custom rifle building—excessive headspace creates catastrophic risk, from brass rupture to dangerous gas blowback. This GO gage measures the maximum allowable headspace for the 350 Legend cartridge, working as part of a matched pair with a NO-GO gage to establish the safe operating window of a rifle chamber.

Forster Products has manufactured precision gages for professional gunsmiths since the mid-20th century. The 350 Legend headspace gage is calibrated to SAAMI specifications, the American ammunition and firearm safety standard. Weighing just 0.08 lbs with compact dimensions of 3.5 x 0.75 x 3.5 inches, this tool fits easily in a gunsmith's bench kit or reloading setup. Consistent use of both GO and NO-GO headspace gages catches potential chamber issues before they reach the firing line—preventing accuracy degradation, bolt-face peening, and brass failure. For anyone building, customizing, or reloading for a 350 Legend rifle platform, proper headspace verification is non-negotiable.

This gage is essential for gunsmiths, ammunition reloaders, and precision rifle builders working with modern intermediate cartridges. The 350 Legend—a short-action rifle round gaining adoption in hunting and sport shooting—demands the same chamber control as any centerfire rifle. Whether you're doing a barrel swap, custom building, or validating ammunition, headspace measurement is the quality control step that separates safe loads from dangerous mistakes. Forster gages are the industry standard for this critical task.
