Abstract
A tube with a conical mouth slides over the neck of an ammunition cartridge and is pressed against the shoulder to align the case. A neck reamer translates and rotates within the tube, the tip being inserted into the neck. Both mouth and tip are replaceable, come in different sizes, and come with smooth or abrading surfaces. The tip and the mouth are coaxial. The mouth perfects the shoulder surface and the tip perfects the neck interior. This results in a cartridge case having a neck with an interior wall that is a perfect cylinder that is coaxial with the perfected exterior of the conical shoulder.
