My sustained throughput on my progressive (RCBS Pro 2000, auto indexing) is approximately 275 RPH. That includes replenishing primers, powder, breaks, going to the garage to get more brass if needed, etc. It assumes I have set the press up for that caliber and everything is "ready to go" (i.e. brass prepped if necessary). I don't have a bullet or case feeder. 4 hours is about the max I'll go in one session.
My sustained throughput on my single stage is about 80 RPH, loading in 50 round batches, assuming I'm dropping straight from the hopper. If I'm trickling, it's about 40 - 50 RPH.
