RCBS Pro Chucker 5 Shell Plate - #20

The RCBS Pro Chucker 5 Shell Plate #20 is a precision reloading component designed for serious handloaders who demand reliability and accuracy in their ammunition assembly process. This shell plate is engineered specifically to configure and operate within RCBS Pro Chucker 5 and Pro Chucker 7 Auto Index Progressive presses, serving as the critical interface between your press and your brass. Reloaders choose RCBS shell plates because they enable fast, consistent indexing of multiple cartridge cases through the complete reloading cycle without loss of precision.

This shell plate features precision manufacturing tolerances that ensure perfect alignment and indexing during the automatic progression of your reloading station. The #20 designation indicates this plate is calibrated for a specific cartridge family within RCBS's indexed system, allowing the auto-indexing mechanism to advance your press accurately from one reloading station to the next. At 0.48 lbs with compact dimensions of 3.8 × 0.45 × 4.25 inches, the shell plate is durable steel construction designed to withstand thousands of reloading cycles while maintaining dimensional accuracy that directly impacts case concentricity and final cartridge quality.

Progressive reloaders who operate Pro Chucker 5 or Pro Chucker 7 systems benefit most from having dedicated shell plates for each caliber they load regularly, eliminating setup time and the risk of misconfiguration between caliber changes. The Auto Index feature depends entirely on proper shell plate installation and compatibility, making genuine RCBS replacement and spare plates essential for maintaining operational consistency. Installation is straightforward—the plate mounts directly into your press's indexing mechanism, and compatibility is guaranteed when matched to your Pro Chucker 5 or Pro Chucker 7 equipment.
