RCBS 3-Die Taper Crimp Set Group C Straight Walled Rifle Cartridges .400 Legend
$101.24
The RCBS 3-Die Taper Crimp Set for .400 Legend is purpose-built for reloaders working with straight-wall rifle cartridges. If you're loading .400 Legend ammunition—whether for hunting with modern straight-wall rifles or target work—this die set gives you the precision tooling to produce safe, consistent rounds. RCBS dies are manufactured to tight tolerances and hardened to handle the demands of repeat reloading, and this set is made in the USA.
The three-die system divides the loading job into focused steps. The hardened steel Sizer Die reduces fired cases to proper dimensions and removes spent primers in one stroke—though you'll need to lubricate cases before sizing. The Expander Die then opens the case mouth to the correct diameter for bullet seating and applies the slight flare or bell needed for reliable feeding. Finally, the Taper Crimp Seat Die seats your bullet and applies the taper crimp that .400 Legend headspacing demands.
This is a no-frills, proven approach to straight-wall rifle reloading. The set ships in RCBS's familiar green storage box, keeping your dies organized and protected. For handloaders stepping up to .400 Legend or those familiar with RCBS quality, this die set pairs with standard reloading presses and handles the core operations without extra bells that many reloaders don't need.

Frequently Asked Questions
What do I need to know about case lubrication with this die set?
The Sizer Die requires cases to be lubricated before sizing. This is standard practice for straight-wall rifle cartridge reloading and helps cases pass through the die smoothly while protecting both the case and die from wear.
Is this die set compatible with my .400 Legend rifle?
This die set is designed specifically for .400 Legend straight-wall cartridges. Confirm that your rifle is chambered in .400 Legend before ordering. The set works with standard single-stage and turret reloading presses.
What's included in the box?
The set includes the three dies (Sizer, Expander, and Taper Crimp Seat), and they arrive in RCBS's green storage box for protection and organization.
Can I use these dies for other straight-wall cartridges?
No. Dies are cartridge-specific. This set is sized and configured for .400 Legend only. You'll need a separate die set for any other cartridge.
