The RCBS APS Bench Primer Rod Large (SKU: R784112) is a precision-machined, heat-treated hardened steel replacement priming rod designed specifically for the RCBS Auto Priming System (APS). Operating as an internal punch component, it transfers mechanical leverage directly from the tool handle to seat primers squarely and to a uniform depth within cartridge case primer pockets. It integrates directly with 25-round APS plastic strip carrier feed mechanisms, cycling one primer per handle stroke.

Key Features

• Direct System Integration: Engineered specifically to interface with the RCBS APS Bench Mounted Priming Tool feed mechanism, pushing individual large primers out of color-coded APS strips directly into the case head.
• Durable Tool Steel Construction: Manufactured from heat-treated, hardened steel to resist wear and deformation during repetitive, high-volume bench priming cycles.
• Consistent Seating Depth: Provides direct mechanical leverage transfer to ensure primers are seated squarely to uniform depths across large-calibre rifle and pistol brass.
• Purely Mechanical Operation: Requires no electrical connections or external power sources, functioning reliably within standard reloading workshop environments.

Who is the RCBS APS Bench Primer Rod Large for?

• Reloaders replacing worn large primer rods — Installs into existing setups to restore uniform seating depth for boxer primers measuring approximately 0.210-inch (5.33 mm) in diameter using a dedicated bench priming tool replacement rod.
• Reloaders converting APS bench priming setups for large rifle or pistol primers — Converts an APS bench unit from small-primer configuration to handle large primer pockets with an exact 5.33 mm (0.210-inch) diameter interface.

Less suitable for: Cartridge brass with small primer pockets measuring approximately 0.175 inches (4.45 mm) in diameter, which require a dedicated small primer punch to avoid damaging the anvil or pocket walls, or standard non-APS tube-fed automatic priming tools, press-mounted ram prime units, and handheld priming tools, which require tool-specific non-APS primer punches.
