Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

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.
