I'll be goin duck hunting this coming friday and i have boxes of 1, 2, and 4 shot, but all of them are 2 3/4". i do have some 3" BB shot, but im saving that for goose hunting if i can. I'll be hunting in a spot where most of the shots will be fly-bys and some will be quite a poke. I wont claim to be an expert on shells, but i assume the 1 shot would have the farthest range, but 4 shot would have the most pellet count. which would you use if you were in my shoes? ive been told most of the ducks will be smaller species (teal, wood, etc). Also,i'm in college so goin out and buying some boxes of 3" shells when i have 4-5 boxes of 2 3/4" is not an option. I'll be shooting a remington 870 wingmaster if that helps at all. thanks alot everybody!
