The RCBS Pow'r Pull Impact Bullet Puller features a solid one piece body, innovative 3-jaw chuck that firmly grips the case rim. Just tap it on a solid surface as you would a hammer, and the powder and bullet drop into the main chamber for re-use. A soft cushion prevents any damage to bullet. Works with most centerfire cartridges from the 5.7x28mm FN and 22 Hornet up through the Winchester Short Magnum and Remington Ultra Magnum family of cartridges.
