The Redding 80191 Three Die Set For 45 Colt And 454 Casull Reloading is a precision-machined Series-A standard steel die set designed to prepare and assemble straight-wall revolver and lever-action ammunition. Machined from heat-treated alloy steel on precision lathes, this three-die set handles the separate operations required for straight-wall brass: full-length sizing with decapping, case mouth expansion, and bullet seating with an integrated roll crimp. It accommodates both low-pressure .45 Colt and high-pressure .454 Casull cartridges using industry-standard 7/8"-14 threading compatible with standard single-stage and turret reloading presses.

Key Features

• Three-Die Straight-Wall Architecture: Separates brass processing into full-length sizing/decapping, case mouth flaring with a dedicated expander plug, and bullet seating with a built-in roll crimp ring.
• Dual-Calibre Tooling: Reloads both .45 Colt and .454 Casull cases through standard press die-height adjustments.
• Integrated Roll Crimp: Bullet seating die incorporates an internal crimp ring designed to secure bullets against jump and setback during heavy firearm recoil.
• Alloy Steel Construction: Machined from heat-treated alloy steel to maintain tight internal dimensions across extended reloading runs.
• Standard Thread Mount: Utilises standard 7/8"-14 threads to mount securely in standard Australian workshop reloading presses.

Who is the Redding 80191 Three-Die Set for .45 Colt and .454 Casull for?

• Handgun hunters — provides an integrated roll crimp in this reloading three die set to firmly lock .452" diameter bullets into heavy-recoil .454 Casull hunting brass.
• Cowboy Action shooters — delivers dedicated case mouth expansion and full-length resizing across standard alloy steel dies to reliably feed .452" diameter cast or jacketed lead bullets into .45 Colt revolvers and lever-action rifles.
• Single-stage and turret press reloaders — mounts directly into standard single-stage and turret presses utilising industry-standard 7/8"-14 threading within a total shipping weight package of 0.5–0.6 kg.

Less suitable for: High-volume progressive reloading where applying case lubrication is inefficient (carbide three-die sets fit this application better by eliminating case sizing lube), or maximum-charge .454 Casull loads requiring a separate profile crimp die to prevent bullet deformation under extreme crimping pressure.
