Rather than purchase reloading parts separately the RCBS Power Punch Decapping Assembly is a more economical option. Made for various calibers and diameters this decapping assembly boasts an extremely hard and slick expander button complete with a positioning sleeve for easy adjustment.

The button also makes extraction through the case neck easier which helps prevent problems of stretching but also reduces case trimming. As a result the case will have longer life and accuracy is enhanced. For self-centering in the case neck the assembly also includes the free-floating button design.
