RCBS AmmoMaster/ Piggyback Shell Plate #39 38 Colt Su

The RCBS AmmoMaster/Piggyback Shell Plate #39 38 Colt Su is a precision reloading component designed for serious handloaders who demand consistency and accuracy in ammunition production. This shell plate is engineered to work seamlessly with RCBS's 5-station progressive reloading systems, ensuring each cartridge is properly positioned during the entire reloading cycle. Whether you're a competitive shooter, law enforcement armorer, or dedicated handloader, this component is essential for maintaining the tight tolerances required in modern ammunition manufacturing.

The shell plate's primary function is to align the case with reloading dies with the precision that separates quality reloads from problematic ones. Manufactured to RCBS's exacting standards, the plate features machined indexing surfaces that guide the case through each progressive station—decapping, resizing, powder charging, bullet seating, and crimping. The compact 2.75 x 2.85 inch footprint integrates directly into the AmmoMaster or Piggyback press head, rotating in synchronization with the reloading cycle to position each case with repeatable accuracy that impacts both velocity consistency and pressure curves.

This shell plate (#39 configuration) is specifically calibrated for 38 Colt ammunition, making it the correct choice for operators and reloaders working with that cartridge. The lightweight 0.33-pound design reduces press wear while maintaining the rigidity needed to handle repeated indexing cycles. Installation requires no special tools—the plate mounts directly to your AmmoMaster or Piggyback system's turret head. For high-volume reloaders and military/law enforcement armorers maintaining departmental ammunition stocks, this component ensures repeatability and reliability across hundreds of rounds per session.
