RCBS AmmoMaster/ Piggyback Shell Plate #20

The RCBS AmmoMaster Piggyback Shell Plate #20 is a precision reloading component engineered for shooters who demand repeatability and accuracy in ammunition production. This 5-station shell plate is the backbone of progressive reloading systems, ensuring perfect case alignment during each stage of the reloading process. Whether you're a competitive shooter, hunter, or law enforcement armorer maintaining duty ammunition, this shell plate delivers the indexing precision required for safe, consistent loads across high-volume production runs.

The shell plate's design positions each cartridge case directly beneath the corresponding reloading die with zero runout tolerance, eliminating common operator errors that lead to inconsistent powder charges or seating depth variation. The #20 configuration accommodates specific cartridge families, allowing seamless station-to-station progression without manual repositioning. Machined from hardened steel and engineered to RCBS tolerances, this component resists the mechanical stress of thousands of press cycles while maintaining dimensional stability—critical for maintaining powder measure accuracy and bullet seating consistency that separates precision reloads from mediocre ammunition.

Reloaders upgrading existing AmmoMaster systems or building new progressive setups will find the #20 plate compatible with standard RCBS 5-station turrets and indexing mechanisms. Armorer operations and high-volume handloaders benefit most from this component's reliability—it's the foundation preventing costly press jams or misindexed rounds. Installation requires no special tools; it seats directly into the turret assembly. For shooters pursuing sub-minute-of-angle accuracy or maintaining large ammunition inventories, proper shell plate selection is non-negotiable, making this RCBS component an essential investment in reloading system integrity.
