The Redding 84294 Deluxe Custom Die Set For 308 Marlin Express is a precision mechanical reloading kit engineered specifically for processing .308 Marlin Express bottleneck rifle brass. Machined from heat-treated alloy steel on precision lathes, this three-die set includes a full-length sizing die with a decapping rod assembly, a neck-only sizing die, and a bullet seating die with an integrated crimping ring. Built with standard 7/8"-14 TPI threading, it integrates directly into standard single-stage and progressive reloading presses to decap, resize, seat 0.308" (7.82 mm) diameter projectiles, and secure them with a uniform crimp.

Key Features

• Dual Sizing Configuration: Includes both a full-length sizing die for restoring factory-dimension chambering in lever-action rifles and a neck sizing die for extending the working life of fire-formed brass.
• Integrated Bullet Seating and Crimping: Applies a consistent roll or taper crimp during projectile seating to prevent bullet setback in tubular magazines under recoil.
• Precision Construction: Heat-treated alloy steel construction, machined and hand-polished to match exact SAAMI chamber specifications.
• Standard Thread Mounting: Built with 7/8"-14 TPI threads to fit all standard reloading presses.

Who is the Redding 84294 Deluxe Custom Die Set For 308 Marlin Express for?

• Handloaders loading for 308 Marlin Express lever-action rifles — Seats 0.308" diameter projectiles and applies a dedicated crimp via the seating die, while the full-length sizing die restores case geometry on 7/8"-14 TPI presses to ensure reliable feeding and extraction in tubular-magazine actions.
• Reloaders requiring both full-length and neck-sizing options — Delivers dual-die versatility within a single deluxe custom reload die set, providing a dedicated neck sizing die to minimise brass fatigue on fire-formed cases alongside a full-length sizer that returns .308 Marlin Express brass to standard dimensional tolerances.

Less suitable for: Reloading standard .308 Winchester or .307 Winchester ammunition, as differences in shoulder angle, rim dimensions, and case length make this tooling incompatible; handloaders processing those cartridges require calibre-specific .308 Winchester or .307 Winchester die sets.
