Depends on where and what type of waterfowl. I use #2 steel on smaller rivers, swamps, #1 steel on larger rivers and BB in corn fields for Geese. We have mainly Mallards, but there are plenty of wood duck, Ruddy ducks, in swamps. My normal duck load when hunting Mallards is #1 steel, it works fine on geese up close also. Decoys and calls are a must! I have a dozen Mallards and 2 geese I use. Calls are standard Quacker, whistler for swamps, and goose for fields. H.S. makes some good ones for beginners. Shotguns, I use a Mossberg 500 24" barrel w/ an improved choke for rivers/swamps. For fields, full choke in a 28" Charles Daly auto. If you buy decoys, Buy heavy line and anchors. Ice fishing line (braided) works well. The anchors they come with are fine for a still pond, but a moving river, no way.
