The Hornady Precision Shell Holder #33 (Item #390573) is a precision-machined reloading accessory designed to secure specific rimmed and semi-rimmed brass cases firmly during handloading operations. Manufactured from heat-treated solid steel, it locks cartridge cases into place with tight tolerances during decapping, full-length resizing, priming, and bullet seating. Its standard universal T-slot mount ensures direct fitment across single-stage reloading presses, turret presses, hand priming tools, and case trimmers across major brands.

Key Features

  • Precision-Machined Steel Construction: Lathe-turned from solid steel bar stock and through-hardened to prevent rim tear-through and resist deformation under heavy sizing pressure.
  • Radiused Case Mouth: Engineered with a wide, rounded opening edge that allows smooth case insertion without catching or snagging the brass case rim.
  • Universal Press Interface: Conforms to standard universal ram-mount slots, providing cross-brand compatibility with presses and accessories from Hornady, RCBS, Lee Precision, Lyman, and Redding.
  • Single-Case Capacity: Holds 1 cartridge case rigidly aligned per operation to maintain consistent shoulder bump and seating depth.

Who is the Hornady Precision Shell Holder #33 for?

  • Vintage Lever-Action and Sporting Rifle Shooters — Requires precise rim engagement to full-length resize and reload .303 Savage cases without stretching or tearing legacy brass rims.
  • Specialised Calibre Handloaders — Requires dedicated case-head support to safely process .356 Winchester and .307 Winchester cartridge cases on standard single-stage and turret reloading presses.

Less suitable for: Reloading standard rimless cases such as .308 Winchester or .30-06 Springfield (which require a Hornady #1 shell holder), reloading standard .303 British cases (which require a Hornady #11 shell holder), or running high-volume reloading setups on progressive presses, which require multi-station progressive shell plates rather than single-case universal shell holders.
