The Redding NxGEN Pro Series Carbide 3-Die Set for .38 Super Auto is an unpowered, mechanical reloading toolset engineered specifically for progressive reloading presses. Built around the industry-standard 7/8"-14 thread interface, this set provides dedicated full-length sizing, bullet seating, and taper crimping operations for .38 Super Auto brass utilising .355" diameter projectiles. By separating the seating and crimping stages across independent dies and eliminating the traditional expander die, it integrates directly into multi-station progressive machines where case mouth expansion occurs at the powder drop station.

Key Features

• NxGEN Titanium Carbide Sizing Ring: The full-length sizing and decapping die resizes straight-wall handgun brass without requiring case lubrication.
• Progressive-Optimised Lead-In: Both the seating and crimping dies feature wide, radiused entry mouths to ensure smooth, hang-up-free case alignment during rapid progressive cycling.
• Independent Seating and Crimping: Uses a dedicated PRO-ST seating-only die and a separate CR taper crimp die to seat bullets to exact overall length before applying uniform crimp, preventing bullet shaving and case buckling.
• Standard Press Interface: Features standard 7/8"-14 threads for compatibility with conventional progressive and turret reloading presses.

Who is the Redding 38 Super Auto Pro Die Set for?

• IPSC Open Division handgun competitors — who need to load high volumes of .38 Super Auto ammunition on progressive presses using standard 7/8"-14 thread toolheads to reliably feed .355" bullets under match conditions.
• Target shooters — demanding consistent overall length and taper crimping across high-volume batches of .38 Super Auto cartridges loaded with .355" diameter projectiles to ensure smooth semi-automatic feeding.

Less suitable for: Handloaders processing other .38 or .357 chamberings (such as .38 Special, .357 Magnum, or .357 SIG), or single-stage press operators who require a dedicated case mouth expander die included in the box; a standard 3-die handgun set containing a separate expander die is better suited to single-stage workflows.
