Redding 300 Wsm Body Die
The Redding 300 WSM body die is a specialized reloading die built for handloaders who work up ammunition in this powerful short-magnum cartridge and need to extend case life. Unlike full-length sizing dies that resize the entire case, a body die focuses on what matters most after repeated firings: restoring the case body to proper dimensions and bumping the shoulder back for reliable chambering, all without touching the neck. This targeted approach is invaluable once your brass starts feeling tight in the chamber—a common issue as cases accumulate rounds and the body work-hardens.
The Redding 300 WSM body die is designed for precision and efficiency. It uses a simple, robust design without internal parts, meaning fewer things to wear out or adjust. The die is meant to work in tandem with your existing neck die: run fired cases through the body die first to resize the body and shoulder, then finish with your neck die to set proper neck tension. This two-step process gives you more control over case dimensions and can breathe new life into brass that would otherwise be relegated to the scrap pile.
If you're running a high-volume 300 WSM reloading setup or just want to maximize every piece of brass you've collected, the Redding body die is a smart addition to your die collection. It's the kind of tool that separates careful reloaders from casual ones—and it pays for itself quickly when it means you don't have to buy new brass.

Frequently Asked Questions
Do I need a separate neck die to use this body die?
Yes. After running cases through the Redding 300 WSM body die to resize the body and shoulder, you'll need to run them through your neck die to set proper neck tension. The body die is designed to work as part of that two-step process.
When should I use a body die instead of a standard full-length die?
A body die is most useful when fired cases begin to feel tight in the chamber or have become difficult to chamber after multiple reloads. Rather than sizing the neck (which can cause unnecessary work-hardening and premature case failure), the body die focuses only on the case body and shoulder, preserving neck life.
What caliber is this die for?
This is a Redding body die sized and configured specifically for the 300 WSM (300 Winchester Short Magnum) cartridge.
