Reloading your own ammunition, while fun and practical and possibly the single geekiest gun-related activity there is, is not something to be done casually.
Especially on a single-stage press, reloading well and safely demands almost as much focus as shooting itself. You'll hear folks say that the most relaxing thing about shooting is that when you're shooting, you're not doing anything else; your mind's completely focused on the front sight and the trigger and the target, not "Did I remember to pick up a gallon of milk?" or "Where are we going to get a sitter Friday night?" Reloading on a single-stage press is the same way; it demands total absorption. On a progressive press, you might get away with having the radio on in the background, but if you're interested in not turning your firearm into shrapnel, your head still needs to be in the game.
Thus, when I asked Les Jones if he'd gotten into reloading yet, his answer made me happy. A man's got to know his limitations.
