A goose, which has been feeding on some fine GA. corn, ought to be good eating. A bird is only as good as what it is eating. One year we had a large number of Brant where I hunted. I quickly learned that if they came from the south east that they were fair table fair, but if they came from the north east that they would be inedible due to getting into a under water plant which locals called sea-skunk-cabbage. If it got on your hands it would take days for the stink to fade. If eaten by the Brant, nothing would make them fit to eat.

I know the real reason you have this long range artillery piece, you have decided that 100 yard Dove are going to never escape your fields. Long range Ducks are only practice for even longer range Dove. Good hunting and better fun.
