Redding Reloading Equipment
The Redding 300 Remington Ultra Magnum bushing die set is built for reloaders who demand precision and consistency in their long-range rifle ammunition. This three-die set combines Redding's proven Type S bushing system with a competition-grade seating die, giving you the control to load match-quality rounds for hunting, precision rifle competitions, or long-range range sessions with the 300 RUM.
What sets this die set apart is the interchangeable bushing design. Rather than adjusting a fixed sizing ring, you swap bushings to dial in neck diameter and tension in 0.001" increments. This means you can fine-tune brass control without over-working the case neck—a common cause of premature brass failure. The bushings come hardened, with optional titanium-nitride (TIN) coatings available if you want extra lubricity and durability. Since they float freely on the case neck, they self-center for repeatable sizing accuracy that shows up in your groups.
The Type S full sizing die handles the body and shoulder; the Type S neck die handles just the neck for reduced case work; and the competition seating die delivers the precise bullet seating control serious handloaders expect. Whether you're developing loads for a new 300 RUM rifle or refining an existing load, this set gives you the precision tools to do it right.
| Cartridge | 300 Remington Ultra Magnum |
| Die Set Type | Type S Bushing Die Set (3-die) |
| Included Dies | Type S Bushing Full Sizing Die, Type S Bushing Neck Die, Competition Seating Die |
| Bushing Material | Hardened steel (TIN coating optional) |
| Neck Tension Adjustment | 0.001" increments |
The Type S full sizing die sizes the case body and shoulder as well as the neck, returning the case to full factory dimensions. The Type S neck sizing die sizes only the neck, which is useful if you're working with fire-formed brass or want to minimize case working during load development.
No. The bushing design requires you to swap bushings to change neck diameter and tension. Each bushing is sized in 0.001" increments. Redding sells bushings separately, so you can build a set that matches your brass and desired tension.
The die set includes the three dies. Bushings are not included and are sold separately; you'll need to select the appropriate bushing size for your brass and reloading goals.
Yes. The competition seating die and bushing sizing system are designed to produce consistent, accurate loads across multiple rounds—ideal for long-range hunting where precision matters.
