I read this thread, then looked across the room at my Dillon 550-B ( http://www.dillonprecision.com/#/content/p/9/pid/23594/catid/1/RL_550B
)and started thinking. What if you had multiple stations with one operation performed at each station? Maybe manually insert a bottle at station 1 and pull a lever to fill it, then manually turn the platform to move it to the next station, insert a bottle at station 1, pull the lever again to fill that bottle and simultaneously perform the next action on the previous bottle (maybe inject a shot of CO2, or place a cap on top, or crimp the cap - could have 3 or 4 stations with a different action performed at each with each pull of the lever, like the Dillon reloader. You'd have to work out a different way of collecting the finished bottles than what the Dillon uses to collect the loaded cartridges, though.
