The Redding 33223 Decapping Rod Assembly with Pin is an exact factory replacement and spare component designed for standard Redding full-length and neck sizing dies. Constructed from heat-treated alloy steel, this mechanical assembly simultaneously punches out spent boxer primers and uniformly expands the internal case neck on the upward press stroke. Sized specifically for standard .224-calibre case geometries such as the .223 Remington, it threads directly into the top spindle of conventional sizing dies to maintain precise depth alignment and reliable case preparation on the reloading bench.

Key Features

• Dual-Action Case Prep: Extrudes spent boxer primers using a standard decapping pin while setting uniform internal neck tension with a dedicated steel expander ball.
• Heat-Treated Steel Construction: Built from durable alloy steel to withstand continuous bench reloading cycles without bending or premature wear.
• Direct Spindle Threading: Screws seamlessly into conventional Redding sizing die bodies for straightforward headspace, depth, and decapping pin protrusion adjustments.
• Replaceable Sub-Assembly: Allows individual sub-components—including the pin and expander button—to be serviced or replaced independently without discarding the main rod.

Who is the Redding 33223 Decapping Rod Assembly for?

• Handloaders reloading .223 Remington and .22-250 Remington ammunition on Redding sizing dies — requires a dedicated .224-inch (approx. 5.69 mm) expander button (Part #39223) matched with standard decapping pin Part #01060 to uniform case neck tension and extract spent boxer primers in standard full-length or neck sizing die bodies.

Less suitable for: Handloaders processing Berdan-primed cases, brass with undersized 1.5 mm target flash holes, or those using Redding Type-S Bushing and Competition Bushing dies; these setups require dedicated bushing-style decapping rods or specialised undersized flash-hole decapping pins without conventional expander buttons.
