The Redding Premium Series Full Length 2-Die Set (MPN 66136) is engineered specifically for reloading 7mm Remington Magnum cartridges utilizing .284-inch diameter projectiles. Designed for handloaders who demand reliable feeding alongside match-grade seating consistency, this 2-die set pairs a full-length sizing die with an upgraded seater die. Built from heat-treated steel with standard 7/8"-14 threading, the set interfaces with standard single-stage and turret reloading presses to return fired magnum brass to factory dimensions while protecting neck concentricity.

• Full-Length Resizing: Restores fired 7mm Rem Mag cartridge cases to standard headspace and body dimensions for smooth cycling in bolt-action rifles.

Who is the Redding 7mm Rem Mag Premium Die Set for?

• 7mm Remington Magnum handloaders pursuing precision long-range accuracy — provides micro-adjustable seating depth via a top-mounted stem graduated in 0.001-inch increments on this 7mm Rem Mag reloading die set, allowing fine control over bullet jump and seating depth.
• Hunters reloading reliable ammunition for bolt-action 7mm Rem Mag rifles — utilizes a free-floating carbide expander button in the 7/8"-14 threaded full-length sizing die to minimize case neck stretching while restoring .284-calibre magnum cases to factory chamber dimensions for dependable cycling.

Less suitable for: Handloaders processing different cartridge families such as 7mm-08 or 7mm PRC, or those requiring fire-formed neck sizing without full-length resizing, who should select a dedicated neck-sizing die set or a custom bushing die system.
