A trimmer for cartridge cases indexes on the shoulder of the case as established by the resizing die and permits a rotating cutter assembly to trim the neck of cases from the inside at a controllable angle. The cutter assembly includes a cutter with a cutting edge for length, a cutting edge for inside chamfer, and an outside deburring edge. There are two alternate embodiments of the invention, one allows for the device to be assembled from several pieces while the other has as many portions as possible cast or machined into a single item.
