RCBS
The RCBS Matchmaster Competition Neck Bushing Set for .308 Winchester is purpose-built for reloaders who demand precision and consistency. This neck-sizing die set brings benchrest and long-range competition-grade accuracy to your reloading bench, letting you dial in exactly the neck tension your ammunition needs without overworking your brass. If you're chasing tight groups and want to extend case life, this is the system serious .308 shooters reach for.
The heart of the Matchmaster system is its interchangeable neck bushing design—a feature long trusted by precision competitors. By swapping bushings, you control how much tension the die applies to your bullet, giving you the fine-tuning that factory dies simply can't match. The sizing die includes a titanium carbide-nitride expander, which cuts down brass buildup on the expander ball and makes extraction smooth and reliable. Case life improves when you're not forcing your brass through a one-size-fits-all die.
The seating die is where the Matchmaster really shines. The loading window and internal bullet retention system mean you drop your bullet in, lower the press handle, and walk away with a perfectly seated round—no balancing bullets on case mouths, no finger safety concerns. The large micrometer knob with oversized markings gives you repeatable, one-thousandth-of-an-inch adjustments you can actually read and feel. Every component is case-hardened steel, precision-reamed and hand-polished, finished in deep blue like a quality firearm.
Made in the USA and backed by RCBS's Limited Lifetime Warranty, the Matchmaster set is an investment in consistent, safe reloading for the long haul. Note that neck bushings are sold separately—you'll want to select the appropriate diameter for your .308 brass and bullet combination.

Neck bushings are sold separately and are selected based on your .308 brass diameter and the specific bullet diameter you're seating. The bushing controls how much tension the die applies to the bullet as it sizes the neck. RCBS offers a range of bushing diameters—you'll choose the one that gives you the light crush fit preferred for precision work.
Yes. The dies feature standard 7/8"-14 threading, which fits any full-size single-stage press (RCBS Rockchucker, Hornady Single Stage, Lee Classic Cast, and similar). The seating die with its loading window works best when you can work at a comfortable pace, so a single-stage or turret press is ideal.
The set includes the neck sizing die with titanium carbide-nitride expander and the bullet seating die with the loading window and retention system. Neck bushings are purchased separately based on your needs.
Instead of trying to balance a bullet on the case mouth or holding it in place with your fingers while pressing, the window allows you to drop the bullet into the opening and lower the press handle. The internal sleeve catches and guides the bullet into alignment with the case, keeping your hands away from the press and ensuring every round seats concentrically.
