We've got a Wheelybird clay launcher and I'm hit and miss with it.
In Basic at Ft. Polk, we were taught Quick Kill shooting starting with BB guns. I think that when I do well with the clays, it's when I stop thinking and some of that training takes over. One afternoon, shooting with my son, I hit about a dozen in a row. On my next turn, I didn't hit any. Also, I do better when I don't call "pull" and just let it be a surprise.
