How many rounds at a time, per day, per week, etc. can you load without hurting yourself. Yeah, I *can load 100 rounds in less than 5 minutes, but I can't sustain that.
I'll do no more than 400 rounds a day after work on my Dillon 650 with bullet feeder and case feeder. On a day off I'll do 300 in the morning and 300 in the evening. Anymore and my elbow and shoulder is toast.
