Quite a few years ago I bought my twin girls, now in college, a dueling tree 22lr reactive target. It has 4 spring loaded steel swingers on each side that are different colored. Really brought out the competitor in those girls. Object of the game is to shoot your side over to your oponents side. Like I said very fun and competitive. I think you can buy 22 size reactive targets for as little as 10.00 up to 50.00 or more.
