RCBS 38 Special/357 Magnum Taper Crimp Seating Die

This die seats the bullet in the case, and then gently squeezes the case around the bullet, forming a perfect taper crimp. Like all RCBS dies, these dies are carefully machined to exacting tolerances, then hardened and hand finished. The result is a quality reloading die that will offer a lifetime of use. Notes: The crimp gently tapers tighter and tighter to hold the bullet in place.It does not affect the overall length of the cartridge.This is very important for semi-automatics where the cartridge headspaces on the case mouth.A Bullet seater is used to push (seat) the bullet down into the case to a specific depth.
