Hey all I am new to the world of duck hunting, I just started because I have recently got the right to hunt some land with a nice creek on it. But we have been haveing troble finding the right combo of choke/Shellsize /how many IN shells. The creek is banked on ether side by 10 foot mounds to protcet the crops from floads. The way we have been hunting them is the 3 of us spread out in front of one side of the bank in a line of about 100 yards then slow creep over the hill and spooke the brids. We have yet to bring down any brids and I am thinking it may be because we arnt hitning any vital areas because the are flying away from us. We get the frist shot of at about 30 yards. I dont want to be wounding any brids so any help would be greatly appriated.
