The RCBS Pow'r Pull Kit features a rugged one-piece body with an innovative 3-jaw chuck that firmly grips the case rim. Just tap it on a solid surface as you would a hammer with the user-friendly ergonomic handle, and the powder and bullet drop into the main chamber for re-use. A soft cushion prevents any damage to the bullet itself. This kit accommodates cases from 5.7x28mm and .22 Hornet up through the WSM and RUM family of cartridges. Covered under the RCBS Limited Lifetime Warranty. Note: Not for use with rimfire cartridges.
