Dillon 550C Progressive Press
The Dillon RL550C is the most versatile reloading machine in the Dillon Precision Products line. It will accommodate the widest variety of cartridges from 32 ACP up to 338 Lapua, 416 Rigby, and 460 Weatherby.
The “C” designation indicates a design change. The upper link arm pivot pins are now threaded in place and have a grease groove around the pin that connects with a lube hole on the end of the pin. You can use a needle fitting on a grease gun to lubricate the upper pivot pins now.
