This popular reloading tool will roll a cannelure groove on any jacketed bullet from 17 to 45 caliber. Completely adjustable for depth and height. One setting will produce thousands of bullets. Also useful for making a second cannelure to lock the core to the jacket to control expansion of hunting bullets. Precision machined throughout. The cutting wheel is hardened to 59C Rockwell, so it will never wear out!All products manufactured by CH4D are made in the USA by Americans at their Mount Vernon, Ohio plant. They also make every effort to find American made tooling and supplies when they make purchases. Unfortunately, it is not always possible to find everything in America anymore, so a small amount of the parts that go into their products are imported.
