The Hornady 480301 is Collet B designed for ARC and Magnum cartridges with 0.438″ and 0.532″ rim diameters, serving as a replacement or additional collet clamp for the Hornady High Speed 3-in-1 Power Case Trimmer. This collet accommodates two sizes of brass and is installed into the sliding handle assembly and held in place by a left-hand-threaded cap, while the large aluminum handle is used to tighten the collet and grab the case rim.
The Hornady High Speed 3-in-1 Power Case Trimmer brings three case preparation steps into one space-saving tool, with a powerful motor spinning at 2000+ RPMs, allowing users to trim, chamfer, and deburr in one quick step. The trimmer features a click-adjustable micrometer for precise and consistent trimming, making it ideal for high-volume reloaders who demand accuracy and speed in their case preparation workflow.
