Redding NxGEN Carbide Competition Pro Series Die Set
The NxGEN Carbide Competition Pro Series Die Set is designed for progressive reloading machines and shooters seeking the best bullet alignment. This full set includes the NxGEN Carbide Sizing Die, the Crimp Die, and the Competition Bullet Seating Die. No expander die is included because many progressive presses expand at the powder drop station. Best for users prioritizing case life, precise chamber fit, and superior bullet alignment on high-volume workloads. The sizing die aims to maximize cartridge-to-chamber conformity, contributing to better function and tighter groups. Choose this if your workflow relies on precise alignment and consistent seating on a progressive press. Caution: There is no expander in this set, so you may need a separate expander if your process requires it for certain bullet types or case necks.
Who this is best for: Competitive shooters, gunsmiths, and reloaders who run progressive presses and demand repeatable seating accuracy.
Why it’s selected
- Carbide construction for durability and long life.
- Dedicated seating die for tight bullet alignment.
