The Sinclair Chamber Length Gauge allows handloaders to accurately measure their rifle's chamber length from the bolt face to the end of the chamber's neck.
Made of 12L14 soft steel, the gauge won't damage the chamber and comes with instructions for repeated use to prevent over-trimming of cases.
It is not suitable for use with thin-necked cases like the 22 Hornet or tight-necked chambers, except for the G-243T, and should not be used in handguns or certain rifles.
