Case trimming is no longer a drudgery. Trim cases simply, with a few turns of the handle. The Trim Pro's spring-loaded level shell holder eliminates the muscle fatigue associated with long hours of tightening a T-bar. The Shell Holder keeps cases securely locked in place and aligned with the cutter. Works with standard pilots and features a micrometer fine-adjustment bushing calibrated for setting exact trim length. Made of die cast metal with hardened cutting blades for a lifetime of reliable use. Includes: Shell Holders: 2, 3, 4 and 10. Pilot calibers: 22, 24, 25, 27, 28, 30, 35, 44 and 45.
