So Ive never been duck hunting. I didnt buy the migratory bird stuff. If I decide to go, What do I need to buy(licnese wise) to be legal and what kind of shells for my 870 ultimag to be legal and what do I need for clothing? I dont have waders. I have muck boots and all kinds of camo. How about a little education for us NON duck hunters that may want to give it a try.
