- Premium Expander: The Redding Premium Expander Die is designed for utility, precision, and high production
- Unique Design: The design of the special expander ensures a proper press fit of bullets, enhances bullet alignment, and increases accuracy
- Propper Press Fit: A radius on the Expanding Die's base eases entry into the case mouth; In addition, the smooth entry radius is followed by the correct expanding diameter for a proper press fit of the bullets
- Bullet Alignment: A concentric ring opens the case mouth slightly larger than the bullet diameter to enhance bullet alignment. The final taper can provide a "bellmouth" on the case mouth when desired, usually when using lead bullets
- Exceptional Durability: A newly designed expander die with the Redding plug coated in Titanium Nitride adds surface hardness, lubricity, and durability. The TiN coating also reduces brass build-up on the expander as well
The REDDING Premium Expander Die has a unique series of processes it provides as it travels into the case itself making it stand apart from the crowd. First a radius on its base eases entry into the case mouth. Next a parallel expander section expands and true's the case internally to create a perfect bearing surface for the bullet as it is seated.
This also adds a more uniform bullet pull and start preassure as well. Next is a small step to properly align the bullet with the centerline of the cartridge case. This positions the bullet for proper contact with the seating micrometer, adding uniformity during the actual seating process. Lastly, a flare to further open the case mouth when using cast bullets so they do not shave lead during the seating process.
