The Sinclair Chamber Length Gauge allows handloaders to accurately measure the true chamber length from the bolt face to the end of the chamber's neck, helping to prevent over-trimming of cases.
Constructed from 12L14 soft steel, the gauge will not damage the rifle chamber and comes with step-by-step instructions for repeated use.
Compatibility restrictions apply: the 22 caliber gauge does not work with thin-necked cases, the 30 caliber gauge is not suitable for the 30-30 Winchester, and tight-necked chambers require the G-243T model.
