The Hornady Custom-Grade New Dimension Full Length Sizer Die (MPN 046528) is a single-station reloading tool designed to decap and resize fired straight-wall cartridge brass back to factory SAAMI external dimensions. Machined to standard 7/8"-14 thread specifications, it threads directly into standard single-stage, turret, or progressive reloading presses. This die is engineered specifically for straight-wall cases taking a 0.357" bullet diameter, covering .38 Special, .357 Magnum, and .357 Remington Maximum cartridges. It pairs with a standard Hornady Shell Holder #6 or Shell Plate #6 (sold separately) to secure brass throughout the mechanical sizing stroke.

Key Features

• Titanium Nitride (TiN) Sizing Ring: Features an internal polished TiN ring that eliminates the need for case lubricant on standard straight-wall brass, preventing galling and surface friction during the sizing cycle.
• Zip-Spindle™ Decapping System: Uses an incremental thread and collet locking system that allows micro-adjustments while preventing slippage when punching out spent primers.
• Sure-Loc™ Lock Ring: Clamps across the external 7/8"-14 die threads to preserve die depth settings between reloading sessions without cutting into the thread profile.
• Single-Stroke Sizing and Decapping: Resizes the full case body length while expelling spent primers on the press downstroke.

Who is the Hornady 38 Spec/357 Mag Full Length Die for?

• Revolver target shooters handloading .38 Special or .357 Magnum ammunition — sized to process straight-wall cartridge brass designed for 0.357" bullet diameters without requiring case lubrication, speeding up processing through standard single-station operations.
• Reloaders processing .357 Remington Maximum brass — engineered to thread into any reloading press utilizing industry-standard 7/8"-14 threads to fully resize lengthened .357 Max cases back to SAAMI factory limits.

Less suitable for: Handloaders who need an all-in-one setup to expand case mouths, seat projectiles, and roll crimp finished rounds—which requires a complete 3-die set containing separate expander and seating dies—or those sizing non-straight-wall cartridges or cases exceeding the 0.357" bullet diameter boundary, who require dedicated rifle sizer dies or larger-calibre straight-wall sizing dies like .44 or .45 calibre dies.
