3-Die Roll Crimp Set - Group E - Straight Walled Cartridges .38-40 Win.

RCBS 3 Die Roll Crimp Set features a steel Sizer Die, Expander Die and Roll Crimp Seat Die. The cases must be lubricated for use with the steel Sizer Die, which sizes the case and de-primes. The expander Die expands the case to the proper diameter to accept the bullet, and it imparts case mouth flare/bell for bullet feeding. The Seat Die seats the bullet in the cartridge case and 'roll' crimps the case to eliminate movement during recoil.

Note: Cases must be lubricated.
