The Forster Neck Reamer #308 (0.3110 inch inside neck reamer) is designed to thin and true cartridge case necks for consistent bullet alignment and chambering. It is intended to be mounted in a case trimmer rather than used as a pilot, allowing targeted removal of excess brass from the neck wall. Constructed for use on fired, unsized cases, the tool promotes uniform neck thickness and improved concentricity.
