The primary difference between the regular RCBS die sets, and the cowboy series sets is the seating stem. Seating stem profiles for spoecific bullets are important for loading maximum accuracy cartridges, so these dies include a seating stem that is common to the specific caliber being loaded. Additionally, these dies feature a heat treated finish, for a more authentic appearance, brass locking rings, and old fashioned packaging.
RCBS Carbide sizing dies are perfect for all straight wall cases, particularly when loading in volume, as they require no lubricant. The carbide sizing ring is extremely hard and also very slick, making stuck cases a thing of the past in all straight walled cases. RCBS reloading dies are extremely high quality dies, with easy to use features that require no special tools. Lock rings are set-screw type, with wrench flats.
RCBS pioneered and developed the 3 Die Sets for straight wall rifle and pistol cases. In the 3 Die Set sizing and expanding (belling) are done in separate dies. The 3 Die Set has a Sizer Die with Decapping Unit, Expander Die for expanding and belling the case mouth and a Seater Die with Bullet Seater Plug(s) for seating and crimping the bullet.
