And how far away is your set? All 3" to 3.5" shells. Passing shots at high flier = full choke/BB'S. Calling them in to land IC/#4's (If set is no more than 20 yards out or you are in a body bag blind amongst the decoys). I found the best all around - Mod/#2's. You may want to load a sequence of diff loads (the birds and weather will tell you what you need). If shooting steel, go up one size from what is listed here all around other than BB's.
