The RCBS 15201 Full-Length 2-Die Set Group A for 300 Weatherby Magnum gives you the core tooling needed to reload this powerful magnum cartridge with precision and confidence. Built around RCBS's proven die design, this two-die set handles the complete sizing and seating cycle for bottleneck magnum cases, bringing your brass back to SAAMI minimum dimensions so each round chambers cleanly and fires safely.
The full-length sizer die does the heavy lifting: it sizes the case body to spec, removes the spent primer via the integrated decapping pin, and opens the neck to accept your bullet. Venting ports in the die prevent the case damage that can happen when air or excess lube gets trapped during the sizing stroke, and the design maintains tight headspace tolerances so your case length stays consistent. Pair that with the seating die—which incorporates a roll crimper to lock the bullet in place as it's seated—and you've got a complete, efficient reloading setup that keeps variables under control from one round to the next.
This is the tooling serious 300 Weatherby Magnum shooters reach for: hunters pushing heavy bullets downrange, long-range competitors, and reloaders who understand that a tight, repeatable reload is where accuracy starts. Standard 7/8-inch-14 thread design fits any RCBS or compatible single-stage or progressive press.
| Caliber | 300 Weatherby Magnum |
| Die Type | Full-length sizer and seater (2-die set) |
| Thread Size | 7/8-inch-14 |
| Case Type | Bottleneck |
| Included Components | Full-length sizer die with expander-decapping unit; seater die with bullet seater plug and roll crimper |
The standard 7/8-inch-14 thread fits RCBS single-stage and progressive presses, as well as most other brands that use standard press dies. Check your press documentation or contact us to confirm compatibility with your specific equipment.
This two-die set provides the sizer and seater dies needed for the core reloading cycle. You'll also need a press, shell holder, powder scale, calipers, and other standard reloading gear depending on your process, but this set covers the essential die functions for 300 Weatherby Magnum.
The vents in the sizer die allow air and excess lubricant to escape during sizing, preventing the case damage that can occur when pressure builds up inside the die. This protects your brass and ensures consistent, high-quality reloads.
Yes. The seater die incorporates a roll crimper that secures the bullet in the case neck at the same time the bullet is seated, combining two steps into one efficient operation.
