I just can't put much faith in that table, Joe. I know O and T are highly respected, but something just does not seem right about it. Look at the full choke in the tables. If the pattern is degrading as they say, at 100 yards there would be a "0" there, or under 10 % at best. Now, if that were so, how do we explain extreme long distance shooting as done by Digweed and others? We know he uses big shot, like 5s, but you still have to hit a pigeon or crow with several pellets to down it. He kills at those distances consistently. I kill doves with an IM at 60+ yards consistently. On two consecutive shoots a couple months ago I killed 6 straight crossers at 60-70 yards. Not where they fell, necessarily, but where they were hit. What are the odds of that happening with a 25% pattern?
Doesn't add up.
