RCBS Pro Chucker 5 Shell Plate - #3

If you reload ammunition on an RCBS Pro Chucker 5 or Pro Chucker 7 auto-indexing progressive press, shell plates are the backbone of caliber changes and press configuration. The RCBS Pro Chucker 5 Shell Plate #3 is a precision-manufactured indexing component designed to work with these specific press models, letting you quickly swap calibers and set up your press for different cartridge families. Shell plates are caliber-specific—each number corresponds to a group of cartridge dimensions—so matching the right plate to your reload setup is essential for reliable, safe operation and consistent primer seating and case handling through the press cycle.

This is a straightforward, durable part that doesn't require expertise to install but demands accuracy in selection. If you own either of these progressive presses and plan to reload multiple calibers, building a small inventory of plates for your most-used rounds saves setup time and prevents mix-ups. RCBS shell plates are manufactured to tight tolerances, ensuring smooth indexing and reliable case advancement with every stroke.

Check your press manual or RCBS's caliber-to-plate chart to confirm that plate #3 matches your intended cartridge before ordering—using the wrong plate can cause feeding issues or unsafe operation.

What is a shell plate and why do I need one?

A shell plate is the rotating indexing component in a progressive press that positions and advances cases through the press stations. Each plate is designed for a specific group of cartridge dimensions. If you reload multiple calibers, you'll need a different shell plate for each cartridge family—allowing you to change calibers without disassembling the press.
