RCBS Taper Crimp Seat Die 40SW

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.
