RCBS - 3-Die Set 375 Winchester - 20604

The 3-Die Roll Crimp Set is designed for reloading straight-wall cartridges, offering a streamlined process for precision. The steel Sizer Die first sizes the case and removes the primer. Cases must be lubricated for smooth operation. The Expander Die expands the case to the correct diameter for the bullet, while also creating a flare or bell at the case mouth to facilitate easier bullet seating. Finally, the Seater Die accurately seats the bullet and applies a roll crimp to ensure secure bullet retention. This set is an excellent choice for loading straight-wall cartridges with consistency and reliability.
