Create Super-Accurate Minimum Headspace Chambers On .30 Caliber Match Rifles
The same special reamers military armorers have long used to cut minimum length chambers on match rifles, giving their shooters the accuracy advantage. The gun's own bolt applies pressure to the reamer while reamer is turned from the muzzle end. When the bolt "drops", the chamber is cut. Improved design cuts the shoulder, neck and throat to prevent neck crimping of the ammo. Use as a finish reamer ONLY. Cut chamber with conventional finish reamer first. Superb quality reamers made to SAAMI specifications.
