RCBS Full-Length Reloading Die Set for .338 Rem Ultra Mag
This two-die set is purpose-built for reloading .338 Rem Ultra Mag bottleneck cases with precision and consistency.
What's Included
- Full-Length Sizer Die with Expander-Decapping Unit
- Seater Die with Bullet Seater Plug and built-in roll crimper
Full-Length Sizer Die
The sizer die brings cases to SAAMI minimum cartridge dimensions for reliable chambering. It performs three critical functions:
- Sizes the outside of the case to proper dimensions
- De-primes spent primers
- Expands the neck to accept new bullets
The die features precision vents that prevent case damage from trapped air and excess lubricant. Headspace is held to minimum tolerances to avoid altering case body length during the sizing process.
Seater Die
The seater die seats bullets to your specified depth while simultaneously applying a roll crimp to secure the bullet. This integrated approach ensures consistent bullet seating and reliable case neck tension in a single operation.
Ideal For
Serious reloaders who demand precision ammunition for the .338 Rem Ultra Mag cartridge. Whether you're handloading for hunting or precision rifle competition, this die set delivers the accuracy and repeatability you need.
