A reloader never knows when a part might break. Be prepared for anything with high quality factory replacement parts that will have your Forster Power Case Trimmer running like new. Notes: The Forster Power Case Trimmer Shaft uses caliber specific pilots (sold separately) to work with different calibers. These pilots are held in the cutter shaft and fit in the case mouth of the cases being trimmed, so the cases are trimmed square to the cutter. Will not work with 17 Caliber Cases, 17 Caliber cases require a 17 Caliber Shaft (Item 625-265)
