We manufacture pilots for our flash hole tool and our Neck Thickness/Variance Gauge. Our pilots are precision machined from stainless steel on CNC turning centers to properly fit new, unfired case necks. Available for rifle and pistol cartridges from 22 thru 45 caliber. Not for use on .50 BMG. 50 BMG flash hole diameter is larger.
