Can I use the Redding 80460 die set to reload shorter .458 Win Mag cases as well as .458 Lott?

No, this 3-die set is engineered strictly for standard SAAMI-spec .458 Lott brass cases (.458

What shellholder do I need to use this die set on my standard reloading press?

The Redding 458 Lott Full Length Die Set requires a Redding #6 standard shellholder (Part #11006), 0.5 to 0.7 kg.

Does this steel die set require case lubrication during the resizing process?

Yes, because these dies are manufactured from heat-treated alloy steel without a carbide sizing ring, external case sizing lubrication is required for all sizing operations to prevent stuck cases.

Redding 80460 458 Lott Die Set

The Redding 458 Lott Full Length Die Set (Part #80460) is a bench-mounted reloading tool designed for processing standard SAAMI/CIP-spec .458 Lott big-bore rifle ammunition. Manufactured from heat-treated alloy steel on precision CNC lathes, this 3-die set delivers dedicated stages for full-length resizing, case mouth expansion, and bullet seating. Built with standard 7/8"-14 threading, the set mounts into standard single-stage and turret reloading presses to produce heavy-recoil hunting cartridges loaded with .458" diameter projectiles.

Key Features

Three-Die Architecture: Dedicated configuration separates full-length resizing, case neck expanding, and bullet seating to properly process straight-wall and minimally tapered .458 Lott cases without case distortion.
Full Length Sizer Die: Part #91460 includes a complete decapping rod assembly (#30097) to decap spent primers and restore fired brass to factory chamber dimensions.
Expander Die: Part #93460 utilizes an expanding plug (#99457) to prepare the case neck mouth for correct bullet seating tension and smooth projectile entry.
Seater Die with Built-In Roll Crimp: Part #92460 features a standard seat plug (#01065) and an integrated roll crimp ring to lock dangerous game solids and soft points securely in place against recoil-induced bullet setback in magazine boxes.
Machined Heat-Treated Steel: Constructed from hardened alloy steel to maintain strict internal tolerances over prolonged batch-reloading cycles (requires external case sizing lubrication).

Who is the Redding 458 Lott Full Length Die Set for?

Dangerous game handloaders in Australia — Requires an industry-standard 7/8"-14 thread and a 3-die configuration to reliably size, expand, and roll-crimp heavy .458" diameter bullets for hunting large game such as water buffalo and scrub bulls.
African safari hunters — Relies on this .458 Lott reloading die set to apply a firm built-in roll crimp to .458" bullet diameter dangerous game ammunition, preventing recoil-induced bullet setback inside the magazine during repeated heavy recoil.

Less suitable for: Handloaders loading shorter .458 Winchester Magnum brass, as the longer internal dimensions of this .458 Lott die set cannot properly size or crimp the shorter case; a dedicated .458 Win Mag 3-die set is required instead.
