The Redding Series A Deluxe Die Set for .300 RUM delivers everything you need to load accurate, reliable ammunition for this powerful magnum cartridge. This three-die set combines full-length sizing with dedicated neck sizing in a single package—practical tooling for reloaders who want efficiency without sacrificing precision. Series A dies are the value option in Redding's lineup, engineered to the same exacting standards as premium models but manufactured with production efficiency that keeps costs down without cutting corners on quality.
Redding machines these dies on Hardinge Super-Precision lathes capable of holding tolerances that ensure your handloads will chamber reliably in any standard SAAMI .300 RUM chamber, regardless of your rifle's action type. Heat treatment in atmospherically controlled furnaces maintains dimensional stability over a lifetime of use. Each die is hand polished, ultrasonically cleaned, and inspected before boxing—the kind of attention to detail that separates quality tooling from commodity brass.
The included storage box doubles as a loading block, and Redding thoughtfully packs a spare decapping pin, hex wrench, and dedicated space for your shellholder inside. All dies feature industry-standard 7/8-14 threaded bodies, so they'll thread smoothly into any compatible single-stage or progressive press. Whether you're fine-tuning loads for hunting, precision rifle competition, or barrel testing, this set gives you the three essential operations—full-length sizing, bullet seating, and neck sizing—in one affordable package.
| Caliber | .300 RUM |
| Dies Included | 3 (full-length sizing, neck sizing, seating) |
| Die Thread | 7/8-14 (industry standard) |
| Series | Redding Series A |
| Includes | Storage box, spare decapping pin, hex wrench, shellholder storage |
Yes. All Redding dies use the industry-standard 7/8-14 threaded body, so they'll fit any standard reloading press designed for that thread size.
Series A dies are manufactured to the same precision and quality standards as all Redding dies, but leverage higher-volume production to offer a lower price point. The heat treatment, hand polishing, tolerances, and performance are identical; only the cost differs.
Redding guarantees that these dies will produce ammunition that properly fits any standard SAAMI .300 RUM chamber, regardless of your rifle's action type.
This deluxe set includes three dies: a full-length sizing die, a neck sizing die, and a bullet seating die. The storage box also includes a spare decapping pin, hex wrench, and space to store your shellholder.
