Shotshell propellants are coarser than rifle and handgun propellants. This seldom poses a problem because both the charge and the case are relatively large. Each case stops under a drop tube that is lowered into the case, delivering a measured amount of propellant. The tube in the case minimizes spilling and facilitates settling of the charge. After charging, the tube withdraws and the case moves to the next position.

Powder Level Verification

In the next dial position, a powder-level detector verifies the newly placed charge.
