Cuts A Smooth, Precise Chamber With Less Chance Of Rifling Damage
Removable (live) pilot greatly reduces the risk of scratching the lands when cutting the chamber to final dimensions, so you get the best possible chambering job for maximum accuracy. Snug-fitting pilot helps provide extra-stable “live center” alignment to maintain proper chamber-to-bore alignment. Precision ground from high speed M7 tool steel for smooth, clean cutting and maximum service life. Includes one pilot for caliber listed.
