For Maximum Accuracy & Results Using Pistol Chamfering Tools
There is a very narrow, (.004") throat diameter range where maximum accuracy is obtained. Go smaller or larger and accuracy will suffer. By simply slipping the Plug Gauge into the barrel throat, it s possible to tell at a glance when you are approaching the correct diameter. Warns you before you go too far. Also valuable as a diagnostic tool for guns brought in with accuracy complaints, (designed for chamfers cut with our tools - may not give a correct reading on guns with other degrees of chamfer). Each gauge is self-piloted, precision-ground, hardened and stepped to show minimum and maximum optimum diameters. 11° and 18° Gauge measures both chamfer angles. Sizes .22RF; .32; .38/.357; .38-40/.40; .41; .44; .45. 5° Ruger-Style Gauge available in .38/.357, .44 and .45 caliber only.
SPECS: 1¼" (3.2cm) long. Steel. Instructions included. 11°-18° gauges measure forcing cones with either angle. 5°, .38/.357 gauge is designed for Ruger .38/.357 s which began using this angle about 1983. Complete Set includes the Rimfire Gauge, all ten Centerfire Gauges and Instructions in a Bench Kit Box.
