The Hornady Precision Shell Holder #53 (MPN 390608) is a heat-treated solid steel reloading component designed specifically for the .404 Jeffery cartridge. Machined to hold the cartridge head square during high-pressure reloading operations, it fits into the standard T-slot rams of single-stage and turret presses from major manufacturers including Hornady, RCBS, Lyman, Redding, and Lee. It features a radiused entry opening that facilitates smooth, snag-free case insertion and removal, helping prevent case rim deformation during resizing, decapping, and priming procedures.

Key Features

  • Calibre-Specific Machining: Cut to fit the distinct rim and extractor groove dimensions of the .404 Jeffery case.
  • Radiused Entry: Features a wide-mouth opening designed to reduce friction and eliminate rim hang-ups during repetitive bench operations.
  • Heat-Treated Solid Steel: Resists bending, stretching, or rim slippage under heavy resizing pressures.
  • Broad Tool Compatibility: Installs into universal press rams as well as matching hand-priming tools and case trimmers without adapters.
  • Manual Mechanical Operation: Requires no electrical power, making it fully independent of workshop power sources.

Who is the Hornady Precision Shell Holder #53 for?

  • Australian Big-Game Safari Hunters — utilizes a solid steel shell holder sized precisely for large-calibre bolt-action brass to manage case prep and handloading for dangerous-game rifles chambered in .404 Jeffery.

Less suitable for: Reloaders working with standard 0.473-inch case heads (such as .30-06 Springfield or .308 Winchester) or belted 0.532-inch magnum brass (such as .375 H&H Magnum and .416 Remington Magnum), who require standard #1 or #5 shell holders; progressive press setups requiring dedicated progressive shell plates; or heavy 1-1/2 inch large-shank reloading presses.
