I've wondered how these shoot.

I have a standard Single Six that shoots great with open sights and a wide variety of ammo. I have only shot it out to about 35 yards so far, but any grouse in that range this fall is going to be in serious trouble!

Is that "grouse on the wing" ??

Nope, same as I hunt them with a longbow/recurve, try to get a shot before they take off. The blues where I hunt don't give you much of a chance before blowing out. Every now and then one will cooperate though.

The Standard one I had shot great as well. Another one of those guns I wish I hadn't sold. whimper whimper, snif snif.
