RCBS Auto Priming Tool

• Single-stage lever system: The RCBS Auto Priming Tool uses a sensitive lever action that gives better feel during primer seating, helping reloaders detect seating pressure changes and maintain more consistent results.
• Automatic tube-fed primer delivery: Primers feed one at a time through the tube system, which speeds up repetitive case preparation work and reduces direct handling of primers during the process.
• Large and small primer capability: With two primer rod assemblies and two primer feed tubes included, the tool adapts to different primer sizes without requiring a separate priming setup.
• Bench-ready metal construction: Its metal build gives the tool the rigidity needed for steady operation, which is especially useful when processing larger batches of brass at the loading bench.
• Made in the USA: Domestic manufacture aligns this priming tool with RCBS's long-established focus on reloading equipment built for regular workshop use and repeatable ammunition assembly.

About the Auto Priming Tool Series

RCBS priming tools are built for reloaders who want a dedicated way to seat primers with more control than improvised press-based methods often provide. Within the RCBS reloading lineup, these tools sit alongside presses, dies, powder measures, and case-preparation equipment as part of a complete handloading system. The series covers different working styles, from portable hand priming tools to more bench-oriented solutions for reloaders who process brass in larger volumes.

The Auto Priming Tool format focuses on speed, repeatability, and cleaner primer handling. Tube-fed primer delivery keeps the workflow moving while reducing unnecessary contact with primers, and the lever-driven seating mechanism is designed to preserve tactile feedback so the operator can feel when a primer is properly seated. That combination makes this style of tool well suited to routine rifle and pistol cartridge preparation, especially where consistent primer seating depth matters for reliable ignition. In practical terms, the series is aimed at reloaders who want a dedicated priming station that fits naturally into a structured bench setup.

About the RCBS Auto Priming Tool

The RCBS Auto Priming Tool is a bench-oriented priming accessory designed for reloaders who want to separate primer seating from the rest of the loading cycle. By using a unique single-stage lever system, it delivers a more deliberate seating stroke and clearer tactile feedback than faster but less sensitive methods. That matters when working through batches of brass where consistent primer seating contributes to uniform ignition and smoother ammunition assembly.

The automatic feed system moves primers through the tube one by one, which helps maintain a steady rhythm at the bench and reduces the need to handle individual primers with oily or contaminated fingers. For practical use, this means less interruption during case preparation and a cleaner process when priming larger quantities of cases. The tool also includes two primer rod assemblies and two primer feed tubes, allowing it to support both large and small primer work without forcing the user into a single-caliber setup.

Its metal construction gives the tool a solid, workshop-focused feel that suits repeated use on the loading bench. With a length of 340.00 mm and a compact height of 71.00 mm, it fits easily into a dedicated reloading station without taking up the space of a full press. For reloaders focused on case preparation efficiency, the RCBS Auto Priming Tool offers a straightforward way to speed up priming while keeping seating feel and process control intact.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name came from “Rock Chuck Bullet Swage,” the original bullet-swaging die that started the business. From that beginning, RCBS grew into a specialist in ammunition handloading and reloading equipment for rifle and pistol cartridges.

RCBS is based in Oroville, California, United States, and its product range covers the core tools used across the loading bench, including presses, dies, shell holders, powder measures, and priming tools. The brand is especially well known for building equipment that supports complete reloading workflows rather than isolated tasks. That background makes RCBS a natural fit for products such as bench priming tools, where consistency, mechanical feel, and compatibility with broader case-preparation routines matter most.
