The Redding 300 PRC Body Die (Redding part no. 75776) is a body die chambered for 300 PRC, built to resize the case body and shoulder of fired brass without contacting the case neck. Because it works the body and shoulder only, it pairs with a separate neck or bushing die so shoulder bump and neck tension can each be set independently, instead of being locked together by a single full-length die. That two-die approach is the standard setup for handloaders prepping brass that’s been fired across multiple rifles or actions, since shoulder bump and neck tension can each be dialed in to the individual chamber rather than compromised by a single fixed-dimension die.

Key Specifications

• Chambered for 300 PRC, sized to that cartridge’s body and shoulder dimensions.
• Built for shoulder bump control, letting handloaders set case shoulder setback to a precise target rather than a fixed full-length dimension.
• Machined from hardened steel for a die that holds its dimensions through repeated resizing.
• Leaves the case neck untouched, pairing with a separate neck or bushing die for full case prep.
• Threaded to the industry-standard 7/8-14 die thread, so it fits any standard single-stage or turret press.

Frequently Asked Questions

Does this die size the case neck? No — a body die resizes only the case body and shoulder, leaving the neck untouched for a separate neck or bushing die to handle.

What is this body die used for? It bumps the shoulder back and resizes the case body of once-fired 300 PRC brass, while leaving neck sizing and tension control to a separate neck or bushing die — the standard setup for precision bolt-gun reloading.
