I'm reminded of when I was a kid hunting pheasants with my 30" full choked BPS pump, because that was all I had. Missed a few close shots because of the tight choke, and ruined a few birds when I connected close too.

The perfect grouse gun? The one you have in your hand.

Otherwise, a 26" 6.2 lb. sk/lt.mod DT 16b would be about ideal in my opinion (like C'man's). You know, if you're into that sort of thing.
