Sitting on the reloading shelf was 48 empty 45-70 cases and some cast bullets. You know the drill: clean, lube, resize, trim & deburr, tumble brass; then bell case mouths, load powder, seat and crimp bullets. This simple activity was s -- l -- o -- w . Resetting dies, trimming cases with a Lee trimmer, dispensing powder and flaring case mouths with a Dillon powder measure mounted in a RockChucker took about 2 hours, not counting tumbler time. I can't imagine loading 100 rounds ONE-step at a time using a RockChucker press and RCBS powder measure. I love my Dillon presses.
