Back when I was gainfully employed I shot at least once a week, firing about 150~200 rounds through two guns. I found that this kept me in pretty much top shape. So, most of my guns stand at around 10,000~15,000 rounds through them. Some of my newer guns at about 5,000 rounds. I've gone through over fifty handguns, so no one gun getss too much usage.
After retiring, I shoot about once every two weeks, and, due to finances, shoot a lot of .22 R.F. now. I always put in a good amount of range time just before hunting season opened.
I don't hunt anymore, and all of my hunting companions are dead now. In fact, I had coffee last Friday with a friend of mine, and he and I are the only two of our old group still living.
