RCBS Full-Length Reloading Die Set for .300 WSM
This two-die set is purpose-built for reloading bottleneck rifle cases and delivers the precision and reliability that serious handloaders demand.
What's Included
- Full-Length Sizer Die with Expander-Decapping Unit
- Seater Die with Bullet Seater Plug and integrated roll crimper
Full-Length Sizer Die
The sizer die brings cases to SAAMI minimum cartridge dimensions, ensuring consistent chamber fit and reliable feeding. It performs three critical functions:
- Sizes the outside of the case to specification
- De-primes spent primers safely and completely
- Expands the neck to accept bullets of proper diameter
Vent ports prevent case damage from trapped air and excess lubricant buildup. Headspace is held to minimum tolerances to avoid altering case body length during the sizing process.
Seater Die
The seater die seats bullets with precision while the integrated roll crimper secures them simultaneously. This two-step-in-one design streamlines your reloading process and ensures consistent bullet seating depth and crimp tension.
Why Choose This Set
RCBS dies are engineered for accuracy and durability. Whether you're loading match ammunition or hunting rounds, this set provides the foundation for consistent, reliable handloads in the powerful .300 Winchester Short Magnum.
