The NECK REAMER is designed to remove excess brass from inside case neck walls and is made from high-grade, wear-resistant tool steel.
It features a staggered tooth design for smooth, chatter-free cutting and should be used after firing with a full load but before neck or full-length sizing.
It is suitable for .45 caliber cases, specifically for bullet diameters .452" (.454-.4545), and neck thickness can be tested by sliding a bullet into a fired, unsized case neck.
