The Redding 260 Rem Ackley Improved 40° Body Die is a dedicated handloading tool designed to full-length resize case bodies and push back the shoulder geometry of fired brass without touching the neck. Engineered specifically for the .260 Remington Ackley Improved cartridge, it features no internal decapping assembly, expander ball, or neck bushings. This design allows handloaders to manage shoulder bump and case diameter independently from neck tension, eliminating unwanted neck runout during the body sizing process.

Key Features

  • Independent Body Sizing: Resizes case body dimensions and bumps the shoulder back to proper headspace while bypassing the case neck entirely.
  • No Internal Components: Contains zero internal parts, eliminating decapping assemblies or expander balls that could work or distort the brass neck.
  • Universal Press Interface: Built with industry-standard 7/8"-14 threads to mount directly into standard single-stage and turret reloading presses.
  • Two-Step Workflow Ready: Integrates into advanced loading sequences alongside dedicated bushing neck dies, allowing brass to be bumped only when chambering resistance occurs.

Who is the Redding 260 Rem Ackley Improved 40° Body Die for?

  • Precision handloaders reloading for wildcat rifles — requires an exact 40 degree shoulder angle bump and body sizing profile tailored strictly for fire-formed .260 Remington Ackley Improved chambers without disturbing dialed-in neck dimensions.
  • Competitive shooters utilizing a two-step sizing workflow — provides case body reduction via standard 7/8"-14 threaded presses to restore easy chambering while leaving case necks untouched for independent sizing with dedicated bushing dies.

Less suitable for: Handloaders seeking single-pass depriming and sizing, shooters running standard 20° .260 Remington factory chambers, or anyone handling loaded ammunition; use a full-length sizing die with an integrated decapping rod on empty fired brass instead.
