I love shooting ZZ birds. In my opinion, it is the most difficult shotgun game, but very addicting. Unfortunately, I have not found a single ring in all of Colorado.
The only place I've ever shot them was in Colorado, but it was over thirty years ago at the old Winchester built trap & skeet range east of Lafyette on hiwy 7. One of the pro shooters & gun fitters at the range had bought a set-up & I found them extremely challenging to shoot. I haven't seen another set-up in the state since then. The man that had the set-up still does gun fitting & instruction at Colorado Clays and I need to ask him about it the next time I run into him.
