The RCBS Full-Length Die Set, Group D, for .32-40 Winchester (RCBS part no. 32501) brings this classic bottleneck cartridge to SAAMI-minimum dimensions in two easy steps. The Full-Length Sizer Die, built with an integrated Expander-Decapping Unit, sizes the outside of the case, removes the spent primer, and expands the neck to accept a bullet, while vents in the die guard against case damage from trapped air or excess lubricant. The included Seater Die, fitted with a Bullet Seater Plug, seats the bullet and applies a built-in roll crimp at the same time, giving .32-40 Winchester handloaders everything needed from sizing through seating.
