I can't remember the last time I went to a range to shoot. As far as shooting off hand goes, the best practice is walking and shooting gophers with someone of equal skill or better. If you want to see improvement and make yourself a good shot under any circumstances, shoot off hand...
Years ago I'd never even heard about "practice". We just called it out shooting.I'd grown up shooting gophers and grouse from about 3 years of age. When I was into my teens I worked many summers on the weekend doing what we called babysitting for a logger. He'd work weekends by himself and needed someone else there for safety purposes in case he were to get hurt. My pay was a 22 rifle and a box of 500 22 LR each day I worked. Most summers I'd go through 10,000 rounds or more. When the big game hunting years came putting a bullet where it needed to go seemed like a natural thing.
