I'm in the process of building my reloading room. Future plans are to get a Dillon 1050. My ceiling height is a touch over 7 feet. How tall is a Dillon 1050 with the bullet feeder and brass feeder?
Give me a couple of hours to get home and I can get you a measurement from bench top to top of case feeder, but I can't help with the bullet feeder.
I can tell you my basement is only like 6' and I can fill the case feeder pretty easily.
With a full stack & primer follower, that's going to be a pretty tight squeeze. With a sitting bench it won't be a problem. Extend your arm straight out from your chest and measure the distance to the floor. Subtract 4" and that'll be the height of your handle. Build your bench accordingly.
