Abstract
A micro-adjustable case neck turning tool which provides the mechanical capability for case neck trimming blade vernier driven vertical displacement adjustment and set in measured increments of 0.0002-inch and interpolated increments of 0.0001-inch for achieving consistent close tolerance trimming and trueing of the outside diameter of a cartridge case neck, thereby to uniformily undersize the same for close tolerance receiving and positioning thereof upon cartridge lock-up within a firearm chamber and thus increase the inherent cartridge factor accuracy by reducing substantially the potential for a mis-aligned angle of incidence in the bullet-to-bore relationship upon discharge delivery of a bullet from the case mouth into the firearm barrel.
