The Redding #07 Competition Shellholder Set (MPN: 11607) is a precision 5-piece mechanical reloading accessory engineered to control headspace and cartridge shoulder bump during full-length resizing. Standard industry shellholders feature a nominal deck height of 0.125″; this set provides matched shellholders with stepped deck heights from 0.127″ to 0.135″. By altering deck depth in precise +0.002″ increments, handloaders can match resized cartridge dimensions directly to a rifle's chamber without altering sizing die depth or backing off the die, eliminating press deflection and die alignment runout.

Key Features

  • Five-Piece Incremental Set: Includes five shellholders stepped in +0.002″, +0.004″, +0.006″, +0.008″, and +0.010″ offsets over standard nominal deck height.
  • Hard Die-to-Shellholder Contact: Allows full contact between the die base and the shellholder ram, maintaining square mechanical alignment throughout the sizing stroke.
  • Distinct Finish and Identification: Features a black oxide finish with clearly engraved offset values on each shellholder.
  • Dedicated Calibre Fit: Machined specifically for the #07 rim profile, matching the 6.5×55mm Swedish Mauser cartridge family.
  • Universal Press Mount: Compatible with standard single-stage and turret reloading press rams, including Redding, RCBS, Lyman, and Hornady models.

Who is the Redding #07 Competition Shellholder Set - 6.5x55 for?

  • Long-range precision handloaders using 6.5×55mm Swedish Mauser — establishes precise cartridge shoulder setback within a +0.002″ to +0.010″ envelope, ensuring cases fit custom or minimum-spec chambers while keeping the sizing die firmly seated against the press ram.
  • Benchrest and PRS shooters seeking consistent headspace and enhanced brass life — provides stepped adjustments up to +0.010″ over the standard 0.125″ deck height, preventing over-resizing and working the brass shoulder only the exact amount required for reliable chambering.

Less suitable for: Handloaders running cartridges outside the #07 rim profile, or rifles requiring zero/negative bump below nominal 0.125″ or exceeding +0.010″ of shoulder relief; these applications require alternative calibre-specific competition sets (such as #1 or #10) or custom-modified standard shellholders.
