I too have a tender shoulder, not in need of surgery, just old. My plan is to motorize my Dillon 650. Just got my Mr Bullet Feeder and will run that as I save up for motor drive. The full blown Mark 7 system is a bit pricey and would have to learn a new press if I would go that route. Just being realistic for me.
I reload mostly in the winter, pulling the handle anywhere from 50 to 100 times a day, building up my bullet inventory. My shooting is less in the freezing weather, so my inventory gets filled up and ready for spring in no time. When I go fully motorized reloading, my routine might or might not change, I'll have to play that by ear. There is still time needed to sort, clean and inspect brass.
Yes lube your brass. I'm sure there is plenty of good lube available, but I've been using the Hornady stuff and it's worked wonderful for me.
