The Redding 80623 260 Remington Ackley Improved Full Length 2-Die Set is a precision reloading tool engineered to resize fired brass and seat .264" (6.5mm) diameter bullets for custom bolt-action rifles. Machined from heat-treated alloy steel, this set matches the 40° shoulder angle of the .260 Remington Ackley Improved wildcat cartridge. It restores fired brass to exact chamber dimensions while maintaining reliable feeding and uniform neck tension across repeated firings.

Key Features

  • Full-Length Sizing Die (#91623): Sizes the case body, bumps the 40° shoulder back to factory headspace, and decaps spent primers using an integrated decapping rod assembly (#33263) and steel expander button (#39263) in a single stroke.
  • Seating Die (#92623): Utilises an internal bullet guide and standard seat plug (#01067) to ensure straight bullet-to-case alignment, along with a built-in roll crimp ring that can be adjusted or backed off for target loads.
  • Standard Thread Mounting: Fitted with industry-standard 7/8"-14 TPI threads, ensuring direct mounting to standard single-stage, turret, and progressive reloading presses.
  • Durable Construction: Weighs approximately 0.5 to 0.6 kg and is supplied in a dedicated dual-cavity plastic storage box.

Who is the Redding 80623 260 Remington Ackley Improved 2-Die Set for?

  • Australian long-range hunters — requires full-length body sizing and shoulder bumping back to the 40° shoulder angle on .264" diameter cartridge cases to ensure smooth, jam-free chambering and dependable feeding from magazines in field conditions using standard 7/8"-14 TPI reloading presses.
  • Precision Rifle Series (PRS) and F-Class target shooters — relies on consistent internal bullet alignment for .264" projectiles and uniform decapping and expanding in a 2-die set to fireform and reload brass for high-volume 40-degree shoulder match rifles.

Less suitable for: Standard factory .260 Remington cases with a 20° shoulder angle, 6.5 Creedmoor, or other 6.5mm cartridges; reloaders chambered for those rounds require dedicated caliber-specific 20-degree full-length dies or standard 6.5mm die sets to avoid improper headspace and shoulder deformation.
