The Lyman Case Length Headspace Gauge .44 Mag (LY-CG44) is a precision-engineered quality control tool designed specifically for ammunition reloaders working with .44 Remington Magnum cartridge cases. Machined from high-quality solid steel using specialized reamers rather than standard chamber reamers, this one-piece, non-adjustable cylinder-type gauge ensures strict adherence to SAAMI-compliant tolerances. For Australian shooters, this purely mechanical tool is an essential addition to the reloading bench. Because it operates entirely without electrical components, it requires no 240V power or Australian (AU) plug, making it fully exempt from SAA or RCM safety certifications and entirely legal for import and use across all Australian states and territories.

Key Features of the Lyman LY-CG44 Gauge:

• Accurate Headspace Verification: Allows reloaders to quickly check the critical headspace dimension from the base of the cartridge to the datum line, ensuring the case sits safely within minimum and maximum limits to prevent dangerous misfires or firearm failures.
• Dual Length and Diameter Checking: Instantly identifies if a resized .44 Mag case exceeds the maximum allowable overall case length—indicating a need for trimming—or if the outer diameter is too wide for smooth chambering.
• High-Quality Steel Construction: Crafted as a solid, single-piece steel cylinder designed to resist wear and maintain precise dimensional tolerances over thousands of measurements.
• Enhanced Brass Longevity: Helps reloaders verify that their sizing dies are set correctly, preventing the over-working or over-stretching of brass to significantly extend the lifespan of reloadable cases.
• Zero Power Requirements: Operates as a completely analog, mechanical measurement tool, ensuring reliability in any reloading environment without the need for batteries or external power.
