I haven't shot them, but I worked at the IHMSA state championship to fulfill my work hours when I was a member at OGC about 10 years ago. Interesting sport, and some really good shooters. Chickens, pigs and rams at 50, 100, and 200 yards, as I recall. I got to be the guy that hides in the little cubby hole towards the end of the 200 yard lane and then runs out to stand the rams back up after they get shot down!
I thought about taking up the sport and even bought an air pistol to shoot the indoor winter league with those guys, but then I discovered Highpower and started down the rabbit hole to madness...
