Shooting any caliber that doesn't involve a varmint at the other end is boring to me now. That being said, my .22 LR bolt gun is awesome on them out to 100 yards, with my longest hit at about 150 yards. Nice, quiet, and deadly with the right ammo.
I can say that a target can still isn't boring.
Tie a string to a tennis or racket ball and hang in the wind so it moves (swings) out at 2-300 yards. It can be interesting even for center-fire guns.
I say lets all remove the warning labels and let nature take its course.
