Stan; What I think I meant to say is I have very little use for a full choke anymore except for trap shooting and occasional dove hunting. I hunt Grouse and Quail as you surmised. No need for much choke there. When I shoot sporting, I usually put the IC chokes in and shoot #7 1/2 shot, rarely changing them. I've found IC is good for a 40 yard shot. That's a pretty long shot in my opinion. Full Definately gives more distance, just how much I don't know.....maybe a consistent pattern to 55 yds? Also Stan, distance is not the only consideration for tight chokes. My live bird gun is set up .030 and .040". We start at the 32 yd line. I would call this gun full and fuller. Distance isn't the reason this gun is choked this way, the reason being if I hit the bird I want it to DIE. Pattern density my friend, not distance.
