Indestructible tool makes it easy to fix mistakes. Improved 3-jaw chuck firmly grips case rim. Rap it on solid surface like a hammer powder & bullet drop into main chamber for reuse. Soft cushion prevents any damage to bullet. Solid one-piece body adds extra strength. Generous handle size adds comfort. Works with most centerfire cartridges from .22-.45. NOTE: Magnum Chuck Assembly for WSM & belted mags.
