This two-die set provides everything you need to reload bottleneck cases for the powerful .300 Remington Ultra Magnum cartridge. Whether you're a seasoned handloader or new to the craft, RCBS dies are engineered to deliver the precision and reliability that serious shooters 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 your cases to SAAMI minimum cartridge dimensions for reliable chambering and consistent performance. It accomplishes three critical tasks:
- Sizes the outside of the case to proper dimensions
- De-primes spent primers safely and efficiently
- Expands the neck to accept your bullet
The die features internal vents that prevent case damage from trapped air and excess lubricant—a detail that separates quality dies from mediocre ones. Headspace is held to minimum tolerances, ensuring the case body length remains consistent during the sizing process.
Seater Die
The seater die seats your bullet with precision while simultaneously applying a roll crimp to secure it in place. This integrated approach saves time and ensures uniform bullet seating depth across all your reloads.
