I shoot handguns 3 to 4 times a month, 100 to 150 rounds per session. First I shoot the ammo in my carry pistol, for two reasons, to refreshen the ammo, and to make sure the pistol is working correctly. That's usually enough to get me "in the groove". Then shoot 20-30 rounds out of a snub nose .38 Special, mostly because I'm still trying to figure out how to shoot the darn thing. This is all at 5 yards. Then back the target out to 10 yards for some serious work with a 22/45, 60-70 rounds. Then depending on my mood that morning, out comes either my 92FS or M1911 for 50 rounds or so for some more serious shooting. Last couple magazines at 15 yards. About one hour time.
Outdoor rifle during the summer is usually a 3 to 4 hour session, all serious trying for those tiny groups at 100 yards, about once a month. Then end the day with some fun time blasting with an AK.
