Shooting is my hobby, so I load a lot for numerous rifles. I load for deer, hogs, prairie dogs, practice, and an occasional competition. When I have 5 or 600 plus rounds to load for a prairie dog hunt, my A&D fx-120 tied to an auto throw and trickier saves me a lot of time and effort. So far (5 years or so?) I’ve had no issues. You enter the charge wieght, and hit start. I have my brass and bullets on a side table. Pick up the dropped powder, put it in the brass, put container back on scale, load bullet, turn around and next powder charge is ready to go.
Need it for accurate loads? No.
Expensive, yes. So if you don’t load a whole lot, then why bother. There are a couple of systems available now.
