RCBS Small Base Die Set - Group A - Popular Rifle Cartridge .300 Win Mag

The Small Base Sizer resizes cases below SAAMI minimum specifications by reducing the shoulder and body dimensions by a few thousandths of an inch, ensuring proper fit in restrictive chambers. It also de-primes the case during sizing. The Seater Die features a built-in roll crimper that secures the bullet simultaneously as it seats it, enhancing cartridge consistency.
