For concealed carry, practice strong and support hand drawing, strong and support hand one handed shooting, one-handed reloads, malfunction clearing, barricade shooting, drills, etc. As much as I can get away with on a range. Practicing on a moving targets or while on the move is not quite as easy to find around here. Fairly easy to blow through 100+ rounds just to rotate through everything once. Shooting sessions for fundamentals too. The more rounds you send downrange, the better your data averages and the more you can analyze your shots, as well as improve. If doing a training course, that could exceed 1000 rounds over two days.
Of course, shooting for fun and shooting for training are two different purposes. Since shooting for fun is fun, I want the fun to last longer than 10 rounds. I can spend all day on my Walter GX1 or 10/22 sending .22lr to the 200 yard line and trying to outsmart wind. My person preferences. If I had more money and time, I'd shoot even more.
