RCBS Full Length 2-Die Set - 300 AAC Blackout

This two-die set is for bottleneck type cases. It consists of a Full Length Sizer and Seater Die has a built-in roll crimper to secure the bullet at the same time it’s seated.. The sizer resizes cases below SAAMI minimums, reducing the shoulder and body by a few thousandths. It also de-primes the case. To seat bullets without crimping, simply unscrew the die until the crimp ring no longer engages the case mouth.
