RCBS AmmoMaster/ Piggyback Shell Plate #3

The RCBS AmmoMaster/Piggyback Shell Plate #3 is a precision-engineered reloading component designed for serious handloaders who demand consistency and efficiency at the bench. This shell plate serves as the critical indexing interface in progressive and single-stage reloading presses, positioning cartridge cases with exacting tolerances required for safe, repeatable ammunition production.

Built to RCBS specifications, the Shell Plate #3 accommodates specific cartridge families through its engineered pocket geometry and precise center-hole dimensions. The plate's compact footprint—measuring 2.95 x 0.6 x 3.1 inches—integrates seamlessly with both AmmoMaster and Piggyback press configurations without requiring extensive press modification. The lightweight construction at 0.34 pounds reduces reciprocating mass while maintaining the rigid steel composition necessary to withstand repeated indexing cycles.

Reloaders standardizing on RCBS progressive systems benefit from quick-change shell plate compatibility, enabling rapid caliber transitions without press recalibration. This plate is purpose-built for various cartridge families, ensuring case alignment that directly impacts powder charge accuracy and primer seating uniformity.
