The Redding 338 Lapua Magnum Competition Bushing Neck Die Set is built for precision-focused reloaders who demand consistency in their rifle ammunition. This three-piece system includes a Competition Bushing Neck Sizing Die, Body Die, and Competition Bullet Seater—each engineered with the exacting tolerances that separate match-grade ammo from good-enough rounds. If you're handloading for long-range competition, benchrest, or hunting with a 338 Lapua, this set gives you the control to hold tight neck dimensions and bullet seating concentricity shot after shot.
The heart of the system is the Competition Bushing Neck Die. Unlike conventional neck sizing, the case is fully supported and centered before the sizing bushing begins its work. As you stroke the handle upward, the case stays cradled in a snug, sliding sleeve while the bushing self-centers on the neck. The decapping rod runs on precision internal guides—much like a firing pin—to keep everything aligned. A micrometer adjustment knob lets you dial in exactly how much neck material you're sizing, giving you repeatable control over neck length. The Body Die handles full-length resizing of the case body and bumps the shoulder back just enough for reliable chamber fit without disturbing your carefully sized neck. The Competition Bullet Seater uses a floating stem design with tolerances so tight that the stem can actually move freely in its guide. This precision fit minimizes runout and ensures bullets are seated straight and consistently.
Serious reloaders appreciate Redding dies because they sweat the details. You'll need to source your own bushings and shellholder, but the investment in a competition die set pays dividends in consistency and case longevity. For 338 Lapua handloaders committed to precision, this is the equipment choice.

| Brand | Redding |
| Die Type | Competition Bushing Neck Die Set |
| Included Components | Competition Bushing Neck Sizing Die, Body Die, Competition Bullet Seater |
| Adjustments | Micrometer adjustments on Neck Die and Seater |
The set includes the Competition Bushing Neck Sizing Die, Body Die, and Competition Bullet Seater. You will need to purchase bushings and a shellholder separately to complete your reloading setup.
The case is fully supported and aligned before sizing begins, and stays cradled in a sliding sleeve throughout the process. The sizing bushing self-centers on the case neck, and the decapping rod is guided by internal die components for precise alignment—similar to firing pin tolerances. The micrometer adjustment lets you control exactly how much neck material is sized, delivering repeatable results.
This competition-grade set is engineered for reloaders who prioritize precision and consistency, making it well-suited for both long-range competition and precision hunting applications where match-grade ammunition matters.
The seating stem is designed with such tight tolerances in its guide that it can float freely, allowing the bullet to find its own center as it's seated. This precision fit minimizes runout and ensures bullets are seated straight and consistently shot to shot.
