The Hornady Full Length Four-Die Set for .500 S&W Magnum (Hornady part no. 546585) is built for this large-bore straight-wall revolver cartridge, using a genuine four-die architecture rather than the three-die layout common on smaller straight-wall calibers. Splitting sizing, expanding, seating, and crimping into four dedicated dies gives handloaders finer control at each step when working with big-bore magnum brass.

Key Specifications

• This is a genuine 4-die set built specifically for .500 S&W Magnum straight-wall brass.
• Splitting the reloading steps across four dedicated dies — rather than three — gives finer control at each step.
• Four dedicated dies cover sizing, expanding, seating, and crimping as separate operations.
• The set is full-length, resizing the entire .500 S&W Magnum case body rather than just the neck.
• The extra die is a meaningful benefit on big-bore magnum brass, where precise control at each step matters more than on smaller straight-wall calibers.
