RCBS Full Length Die Set .300 Win Mag

RCBS Full Length Die Set for .300 Winchester Magnum

This two-die set is purpose-built for reloading bottleneck rifle cases with the precision and consistency 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
• Durable plastic storage box

Full-Length Sizer Die

The sizer die performs three critical functions in one operation:

• Sizes the case body to SAAMI minimum cartridge dimensions
• De-primes spent primers safely and efficiently
• Expands the case neck to proper diameter for bullet seating

The die features precision venting to prevent case damage from trapped air and excessive lubricant buildup. Headspace is held to minimum tolerances, ensuring consistent case dimensions without altering case body length during the sizing process.

Seater Die

The seater die combines bullet seating with a built-in roll crimper, securing the bullet in place during the same stroke. This integrated approach saves time while maintaining the consistency that precision shooting demands.

Quality Construction

Crafted from high-quality steel, this die set is built to deliver reliable performance for hundreds of reloading cycles. The included storage box protects your investment and keeps components organized.

Note: Shellholders are sold separately.
