When I was a kid, my dad would drop me and my best friend off at the local range with our .22's and several bricks of ammo. The shooting range was part of a trap club that was used only 1 one day a week so we picked up clay pigeons and large fragments and set them up at different distances. We took turns calling shots and challenged eachother to take difficult shots. The back berm was 185 yards out and either one of us could hit unbroken pigeons off the berm consistantly. This practice made me a really good shot when I started shooting centerfire rifles a few years later. I still practice with a .22 rifle and probably fire 100 rds of rimfire to each single centerfire I shoot. My best accomplishment with a .22 was hitting a head shot on a squirrel at about 80 yards- I usually shoot them MUCH closer, but this one was sitting out on a limb begging to be shot and I knew I could make it.

BTW I had my MK II pistol out at the range about 2 months ago and decided to shoot a 16" gong set at the 200 yard berm. I was suprised that I could hit it nearly every time with a pistol shooting off hand once I took a couple of shots to walk it onto the gong.
