Which specific calibers does the RCBS Pro Chucker 7 Shell Plate #20 support?

The RCBS Pro Chucker 7 Shell Plate #20 is precision-engineered to hold and index case heads matching the RCBS #20 profile, specifically supporting .45 Long Colt and .454 Casull cartridges. It is designed to capture the standard 0.125-inch case head height required for proper headspacing through the press stations.

Can this shell plate be used on other progressive presses besides the Pro Chucker 7?

No, this shell plate is built specifically to fit the RCBS Pro Chucker 7 index hub and can also be used when configuring the Pro Chucker 5 press. It is not compatible with other progressive press brands like Dillon or Hornady, nor older RCBS models like the Pro 2000.

Does the shell plate require any electrical certification or mains power for Australian workshops?

As a strictly mechanical reloading accessory made from hardened alloy steel, the RCBS Pro Chucker 7 Shell Plate #20 features no electrical components. It requires no power source, 240V compatibility, or SAA/RCM certifications, making it completely safe and straightforward for any manual reloading bench in Australia.

What maintenance is required to protect the hardened steel shell plate in Australian climate conditions?

To prevent rust and corrosion in varying workshop and outback environmental conditions, standard firearm tool maintenance is recommended. A light coat of gun oil should be applied to the precision-machined steel surface after use, and the plate should be stored in a dry indoor reloading room.

Shell Plate 20 - RCBS R88963

The RCBS Pro Chucker 7 Shell Plate #20 (Model: R88963) is a precision-machined reloading accessory designed to secure, align, and index brass cases through progressive reloading cycles. Manufactured from hardened alloy steel, this durable shell plate is engineered to withstand heavy reloading volumes while resisting structural wear. It operates as a critical mechanical component for handloaders using progressive setups, allowing for smooth, reliable indexing without requiring an external power source.

This shell plate functions by holding cases securely in place as they move through the various reloading stations. Designed to fit the proprietary indexing hub of the RCBS Pro Chucker series, it helps handloaders achieve rapid caliber changeovers when paired with a quick-change die plate system. The plate configuration corresponds directly to standard RCBS single-stage shell holder sizing, simplifying the transition between single-stage and progressive reloading setups.
