I usually make an 8 hour training class per month, sometimes more. That's during the summer, in the winter it winds down a bit and there isn't much offered. I've got a little over 100 hours of professionally taught training under my belt right now, I'll be winding down a bit next year and doing less training, but more advanced and more specialized to my needs.
I also compete in a rifle/handgun match once a month (sometimes don't make it every month) which I also consider training. Sort of like a dress rehearsal, actually...gives me time to put the training to use on my own and see what holes still need to be filled in.
For 'practice' (stuff on my own, without a pro instructor) I try to get 10 or so hours in a week. Mostly dry practice lately as I've been very busy. When I do get to the range I'm typically working on fundamentals. At home I do LOTS of draw stroke practice, dry fire trigger control practice, and transitions from rifle to pistol. I also do a lot of reloads.
