Full-Length Sizer Die
The sizer die brings your 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 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 design detail that protects your investment in quality brass. Headspace is held to minimum tolerances, preserving case body length during the sizing process.
Seater Die
The seater die seats your bullet while simultaneously applying a roll crimp, securing the bullet in place in a single operation. This integrated approach saves time and ensures consistent bullet retention.
The Bottom Line
Whether you're a precision rifle enthusiast or a practical reloader, this die set gives you the tools to produce accurate, reliable ammunition for your .338 Winchester Magnum.
