Forster Hot Pilot #264 For Hand Held Neck Turner For .264 Diameter Bullets. At ignition it is imperative for the case neck to expand allowing the release of the bullet. If one side of the neck is thicker than another the bullet will release prematurely causing a misalignment of bullet-to-bore. When this occurs accuracy is dramatically impacted. Mandrels which are the steel points are ground 0.002 to 0.025 inches smaller than the diameter of the bullet providing excellent performance.
