I just hunt them with my Browning light 12(modified choke), 2 & 3/4 sixes with a follow up shell loaded with 4 x 6 or something like that... although I've never shot the second shell. I guess if you're prone to taking long shots you should use more. I don't usually shoot over 25 or 30 yards, but then.... I usually don't do the shooting. I let someone else worry about that. I'm just a backup gunner incase the shooter gets treed which happens more than it should.
