RCBS Automatic Primer Feed Combo for Rock Chucker II

• Automatic primer feeding: Feeds primers one at a time into the primer plug and sleeve, which speeds up repetitive priming work and keeps the process more consistent on compatible presses.
• Cleaner primer handling: The design keeps fingers off primers during feeding, helping reduce contamination from oil or residue that can contribute to unreliable ignition.
• 100-primer tube capacity: A full tube supports longer loading sessions with fewer interruptions, making bench work more efficient when processing larger batches of brass.
• Nylon primer pick-up: The pick-up helps keep primers from falling out during loading, improving handling security and reducing wasted components at the bench.
• Large and small primer capability: The combo includes components for both primer sizes, so one setup can cover a broad range of rifle and pistol reloading tasks.

About the Rock Chucker Series

The Rock Chucker series sits at the core of the RCBS single-stage reloading lineup and is built around a straightforward idea: strong, repeatable press operation for handloaders who value control over each step. These presses are widely associated with bench loading for rifle and pistol cartridges, where careful case preparation, sizing, seating, and priming matter more than maximum output speed. In practical use, the series appeals to reloaders who want a stable platform for load development, routine ammunition production, and general workshop use.

What distinguishes the family is its emphasis on single-stage precision, durable construction, and compatibility with a broad range of RCBS accessories and press-mounted tools. That makes the Rock Chucker platform adaptable: a user can keep the familiar feel of a traditional press while adding accessories that improve workflow for specific operations such as priming. Within the RCBS range, the series is known for giving handloaders a solid mechanical foundation that can be configured for simple, deliberate loading or upgraded for faster bench routines without abandoning the control that single-stage presses are chosen for in the first place.

About the RCBS Automatic Primer Feed Combo for Rock Chucker II

The RCBS Automatic Primer Feed Combo for Rock Chucker II is a press accessory designed to make on-press priming faster and more orderly on compatible RCBS presses. Instead of handling each primer individually, the system drops primers one at a time into the primer plug and sleeve. In practice, that means less interruption during repetitive loading work and a smoother rhythm at the bench, especially when processing larger batches of brass.

A key advantage of this accessory is its approach to primer handling. By keeping greasy fingers off primers, it helps reduce the chance of contamination during the priming stage, which supports more dependable ignition. The nylon primer pick-up also helps prevent primers from falling out during setup and feeding, which improves bench safety and reduces wasted components. With a 100-primer tube capacity, the feed system is suited to longer loading sessions where frequent refilling would otherwise slow the process.

This combo is also practical because it supports large and small primers, giving one accessory broader usefulness across common rifle and pistol loads. For reloaders using a Rock Chucker II or other listed compatible presses, it adds efficiency without changing the familiar feel of press-mounted priming. The result is a more streamlined priming workflow while retaining the control that many handloaders prefer from a traditional single-stage setup.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name comes from Rock Chuck Bullet Swage, the original bullet-swaging die that launched the brand. From those beginnings, RCBS developed into a specialist in ammunition handloading and reloading equipment for rifle and pistol cartridges.

RCBS is still based in Oroville, California, United States, and its product range covers presses, dies, shell holders, powder measures, and priming tools. The brand is especially well known for offering single-stage, turret, and progressive reloading presses, giving handloaders options that range from deliberate precision work to higher-volume loading. That long focus on reloading equipment is what makes RCBS a natural fit for press accessories such as priming systems and Rock Chucker upgrades.
