Best bet is to give up where you are at and get where the birds want to be. If not possible to decoy them, you are basically dove hunting. But you have got to pattern your chokes and get your timing down to hunt like that. You are missing all the fun of duck hunting if you have to shoot them like that. If that is your ONLY option, mail me and will have you pulling them out of the sky in no time. It is easy to bring them down at 60-65 yards if that is your only option. But you are really missing the real deal that way. Me and two of my buddies can sometimes bring down 7-8 greenheads in a single flock and never even wound a hen.
