I did my reloading in the evening, at least a couple of hundred rounds a night. On a low-end Dillon press, that's less than two hours of work. While my daughter was growing up, she would come out to my workshop and help me, which also saved about a half-hour per session. It wasn't a burden.
The most time-consuming part of reloading in bulk is cleaning the brass, but a relatively inexpensive machine does that while you're doing something else. My daughter loaded my primer tubes for me, and kept me supplied with bullets and cases. I pulled the handle and indexed the loader, and refilled the powder measure as needed.
It was a good time to talk to my child about her life, and to teach her things, and just to relate and build a decent rapport.
And then there was 10 or 15 minutes of dry-fire practice, every night. My daughter ran the stopwatch for me, and offered criticisms—usually very perceptive ones, at that.
