I love discussions about choke constriction and how people have reasoned out their choice or adjust their loads to make their chokes much more versatile. I/C will take a lot of game under most shooting conditions if you match your load and shot to your needs. I spent one entire year shooting nothing but I/C for everything from dove, quail, ducks, geese and anything else I happened to encounter. By changing loads I was never under gunned or poorly choked. A few times I did have to be careful of my range and shot selection but far less than one might think.
I've become spoiled with gauge and choke choices. More so when shooting my doubles which give me two choices to select from. In fact I often choose a double not because it might be the best gun for the job but because I get two choke choices on every first shot. Very comforting. Now if I were into bag limits as quickly possible a good black plastic semi shooting all loads from 2 3/4- 3 1/2" Roman candles would be a better choice. But where is the fun in that. I might as well be into shooting paintballs.
