It is also my belief that the only place to use a double duck hunting is in conditions where the shooters stand upright. To me this is a rather boring way to be restricted while hunting ducks.
This is a double gun blog who's hobby is shooting double guns. Nothing wrong with that. I too like doubles. But I don't hunt ducks with them. Take a nice double with floating firing pins. Crud gets into the pin hole and the pin stays protruded upon closure. The gun will fire when it is re closed. The guns we love deserve better then to be subjected to the crud of a duck hunt.
Besides I doubt I'll ever duck hunt again. I'm too old, too beat up and to crippled. The fact that I won't duck hunt with someone who brings along a double really doesn't matter.
