After my shoulder surgery I added a roller handle a Mr. bullet feeder and a endoscope camera with a 7" screen to my Dillon xl750 I can now operate it with either arm and observe the shell plate to see powder level and if a bullet has been dropped in the case mouth. All cases are deprimed with a Lee APP and lubricated with one shot before going in my case feeder this not only speeds things up it also keeps the press much cleaner. This system works so well I feel like I'm cheating. I know spending $600 on accessories for a $700 press sounds excessive but it's loaded over 40,000 rounds in the last three years. At age 76 I am slowing down a bit but not because of my shoulder it's because I'm about out of pre pandemic 2 1/2 cent primers and $20 a pound powder.
