The Hornady Magnum Reloading Block (MPN 480042) is a dedicated bench-top reloading accessory engineered to support large-diameter rifle cases and shotgun hulls. Built from durable moulded polymer, it arranges up to 50 cartridge cases in a structured grid to keep them stable and upright during case preparation, priming, powder charging, and bullet seating. The oversized cavity layout prevents tall, heavy cases from tipping and enables direct visual inspection across the entire batch to verify powder levels and guard against double charges.

Key Features

  • 50-Round Grid Layout: Holds up to 50 large-format cases in a uniform grid for streamlined bench-top workflow and stage-by-stage powder level inspection.
  • Oversized Cavity Design: Extra-wide pocket openings securely accommodate large magnum rifle cases, heavy .50-calibre-class cases, and shotgun hulls up to 12 gauge (as well as 16 and 20 gauge).
  • Stable Bench-Top Construction: Durable moulded polymer build with a shipping weight of approximately 1.335 lbs (605 g) maintains a low-centre-of-gravity platform to prevent tipping on the workbench.
  • Manual Operation: Passive, unpowered workshop design requiring no electrical input, batteries, or specialised mounting hardware.

Who is the Hornady Magnum Caliber Loading Block for?

  • Australian big game magnum rifle reloaders — Organises large-diameter belted and unbelted magnum cases across a rigid 50-round capacity grid, giving reloaders the stable bench-top alignment required to visually verify powder charges in heavy hunting loads.
  • Shotshell and heavy big-bore reloading enthusiasts — Provides oversized cavity slots engineered to seat broad-diameter hulls including 12-gauge, 16-gauge, 20-gauge, and .50-calibre-class cartridges across a 50-round batch without case tipping or interference.

Less suitable for: Standard and medium-diameter rifle cartridges (such as .223 Rem, .308 Win, 6.5 Creedmoor, and .30-06), which sit too loosely in the oversized pockets and cause excessive wobble; reloaders processing standard rifle calibres require a standard universal reloading tray or a calibre-specific CNC-machined loading block with tighter pocket tolerances. It is also not suitable for mobile field use, as it is designed strictly for stationary workbench placement with a maximum batch capacity of 50 rounds.
