The muzzle crown is the last point of contact between the barrel and a fired bullet. A perfectly consistent, concentric crown allows propellant gases to disperse evenly. Any defect in the crown will result in uneven lateral forces on the bullet, causing it to yaw, which ruins accuracy and repeatability. Our piloted Crown Tools form a precisely concentric muzzle crown. They are manufactured from M42 steel for years of trouble-free cutting. The removable pilot design allows for accurate use in a lathe or with a T-Handle.
Be sure to specify a pilot size when you order. (With Radius Crown Tools, the pilot size is actually the tool size as well. If you change the pilot on a Radius Crown Tool for use in a different-sized bore, the resulting radius crown may be unsatisfactory because it is formed at the wrong diameter.)
NOTE: All PTG Reamers and Cutting Tools are designed to work with petroleum-based lubricant. Water-based lubricant can give acceptable results, however the life of the tool will be reduced. For best results use petroleum-based lubricant.
