I also like to shoot longer distances, mostly because it's fun, and I can. I also grew up shooting at 50 and 100 yards at cans, milk jugs, ect.
It taught me trigger control, and it still does. It's nice to know that I CAN hit regularly at those distances, and it is a great time kicking cans around at 50 yards. That being said, I spend a lot of time shooting combat distances, and I train myself to shoot in some different situations as well.
I spend a lot of time by myself at the range, with nobody else around so I can do all the things I want to do. Sometime, I'll practice shooting laying down, kneeling, running from target to target, shooting from behind things, ect...I don't like an audience when doing this, as you can imagine, I'm there to train myself. What the hey, if I throw myself on the ground down in the dirt and shoot targets, some people might think I'm a little nuts if they see this, although I'm sure some would understand, some might not. At any rate, I love shooting long range for fun, and gives me the confidence that I can hit targets at long range. As mentioned above, it could cause some eyebrows to raise if you ever had to shoot someone at longer range (hopefully most of us won't have to ever shot anyone, but it happens) and I'm sure the circumstances would have to be unusual for this to happen. But...if you ever HAD to...you've had the practice.
