I have killed a few birds over 50 yards, although I really do not like shooting them that far. The fartherest one, and I actually put a tape measure on it because I knew it was long, was 58 yards. The gun was a Benelli SBE2 with an Indian Creek choke and Winchester Supreme 3 1/2 inch number 5 shot. I quit using that gun a few seasons thereafter because it kicked too much and the temptation was always there to take those long shots. I much prefer to let that turkey come into 40 yards or less, and make a sure thing shot, than brag about how far I killed one.
