The Redding Universal Decapping Die Kit (MPN: 69500) is a mechanical reloading tool designed to punch spent primers from brass cartridge cases without resizing the case body. Machined from heat-treated alloy steel, this universal system allows reloaders to deprime fired cases before ultrasonic cleaning or wet tumbling with stainless steel pins, ensuring primer pockets are clean while keeping carbon and abrasive grit out of expensive sizing dies. The complete kit includes the Small Decapping Die, the Large Decapping Die, and a dedicated sub-calibre decapping rod assembly.

• Universal Non-Sizing Operation: Extracts spent primers across multiple calibres without touching or working the cartridge brass.
• Two-Die Coverage Envelope: Includes a Small Decapping Die covering .22 to .50 calibre cases up to 2.50" to 2.625" in length, and a Large Decapping Die handling .284 (7mm) to .50 calibre cases up to 3.0" in length.
• Sub-Calibre Rod Assembly: Features a dedicated .17–.20 calibre decapping rod engineered for sub-calibre cases and tight 0.060" (1.52 mm) flash holes.
• Standard Press Integration: Features standard 7/8"-14 outer die threading for compatibility with single-stage and progressive reloading presses.

Who is the Redding Universal Decapping Die Kit for?

• Benchrest and precision rifle competitors — requires flash hole compatibility down to 0.060" (1.52 mm), which this universal decapping die kit handles using its included .17–.20 calibre rod assembly to prevent pin breakage on tight PPC and BR brass.
• Reloaders processing mixed calibers — handles cases measuring up to 3.0" (76.2 mm) in overall length across standard 7/8"-14 presses, allowing continuous pre-wash depriming across varied cartridge batches using a single multi-die package.
• High-volume handloaders — requires depriming brass up to 2.625" (66.7 mm) in length before wet tumbling to expose primer pockets and protect sizing dies from abrasive range grit.

Less suitable for: Berdan-primed cartridge cases featuring twin off-centre flash holes, or extreme magnum cases exceeding 3.0" (76.2 mm) in overall length (such as .338 Lapua Magnum or .50 BMG); these configurations require dedicated Berdan depriming tools or heavy-duty 1-1/4"-12 large-format decapping dies.
