The RCBS Full Length Die Set for 6.5-300 Weatherby Magnum is purpose-built for reloaders who want to produce match-grade ammunition for one of the most powerful magnum cartridges in the field. This two-die set handles both critical steps of the reloading process—sizing and seating—with the precision tolerances that a belted magnum demands. Whether you're handloading for long-range hunting, precision rifle competition, or load development, this set brings your fired cases back to SAAMI minimum dimensions and seats bullets with consistent pressure.
The Full-Length Sizer Die does the heavy lifting: it resizes the case body and neck, decaps the spent primer, and expands the neck to accept your bullet. Venting ports in the die prevent the case damage that can result from trapped air or excess lubricant, while its design holds headspace to minimum tolerances so the case body length stays true. This matters for magnums, where consistency directly affects velocity and accuracy.
The Seater Die seats the bullet and applies a roll crimp in one operation, locking the bullet in place with repeatable force. Standard 7/8"-14 threading fits any modern single-stage press, so you can integrate this set into an existing reloading setup. RCBS die steel and engineering mean the set will handle thousands of rounds without the wear that shows up in budget alternatives.
| Product | RCBS Full Length Die Set for 6.5-300 Weatherby Magnum |
| Model | 31701 |
| Cartridge | 6.5-300 Weatherby Magnum |
| Die Count | 2 (Full-Length Sizer, Seater) |
| Thread Size | 7/8"-14 |
| Included Components | Full-Length Sizer Die with Expander-Decapping Unit, Seater Die with Bullet Seater Plug and Roll Crimper |
Yes, as long as your press accepts standard 7/8"-14 threaded dies. RCBS dies are compatible with nearly all single-stage presses made in North America.
The set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with a built-in Bullet Seater Plug and roll crimper. You'll need a reloading press, primer pocket cleaner, and other standard reloading components to complete your setup.
Case lube is standard practice when full-length sizing rifle cartridges. The vented design of this sizer die helps prevent buildup of excess lubricant, which can cause case damage.
This set handles sizing and seating—the two main steps. You'll also need a press, primers, powder, bullets, and a powder measure or scale to complete your reloading workflow.
