The Redding Competition Bushing Neck Die Set for .25-06 Remington is a three-piece mechanical hand-loading tooling system designed for precision cartridge reloading. Featuring industry-standard 7/8"-14 threads, the set mounts into compatible single-stage and turret presses to size fire-formed brass cases and seat 0.257-inch diameter projectiles with minimal concentricity runout. The system includes a Competition Bushing Neck Sizing Die with top-mounted micrometer adjustment, an alignment sleeve Competition Bullet Seating Die with micrometer control, and a dedicated non-sizing Body Die to set shoulder setback without contacting the case neck. Packaged set weight is approximately 0.9 to 1.0 kg (2.0 to 2.2 lbs).

Key Features

• Dual Micrometer Adjustments: Top-mounted calibrated micrometers on both the neck sizing die and bullet seating die feature 0.001-inch graduations for repeatable depth and tension settings.
• Sliding Sleeve Concentricity Alignment: Internal sliding sleeves support and guide the case and projectile into straight alignment prior to sizing and seating, minimising total runout.
• Modular Bushing Neck Sizing: Compatible with interchangeable standard sizing bushings ranging typically from 0.280 inch to 0.288 inch, allowing precise neck tension adjustment without an internal expander button.
• Dedicated Body Die: Restores full-length body dimensions and bumps the case shoulder 0.001 inch to 0.002 inch without altering adjusted neck dimensions.
• Press Compatibility: Standard 7/8"-14 thread interface ensures fitment across common Australian reloading presses with standard #1 shellholders.

Who is the Redding Competition Neck Die Set For 25-06 Remington for?

• Precision long-range target shooters loading .25-06 Remington — calibrates exact seating depth via 0.001-inch micrometer graduations on the seating die while holding 0.257-inch bullets in a tight-tolerance sliding sleeve to minimise concentricity runout.
• Handloaders seeking benchrest-level concentricity and neck tension control — adjusts brass dimensions using interchangeable bushings from 0.280-inch minimum to 0.288-inch maximum without an expander ball, preventing case overworking on fire-formed .25-06 Remington brass.
• Reloaders firing fire-formed brass exclusively through bolt-action rifles — sizes case necks on standard 7/8"-14 presses and includes a dedicated body die to bump shoulders 0.001 to 0.002 inches when chambering tightness occurs across repeated firings.

Less suitable for: Semi-automatic, lever-action, or pump-action rifles requiring full-length sizing for reliable feeding and extraction; standard full-length die sets with integrated expander assemblies fit these operating mechanisms better.
