I have been Black Powder waterfowl hunting for over 40 years. Prior to that I used modern firearms, so I have all the decoys (some purchased, some handmade). I started shooting lead and switched to bismuth (now shoot ITX) shot. Yes it is expensive, but I would be willing to bet that the cost per harvested duck is lower than the "Sky-busting-long-range-think-they-can-reach-'em-while empting-the-gun" shooters out there. I have harvested, ducks, Canada geese, Ross geese, and Sandhill cranes using 10ga, 12ga cap-locks and 16 gauge flintlock. I met up with a fellow black powder waterfowlers in Katy, Texas for sandhill crane and snow/spec/blue/Ross goose hunting. We had a great time, lying flat in a wet rice paddy while it was raining. As for being easy-- I think you have it wrong, field cameras, sitting in tree stand / ground blind and wait for deer to come into range, boring. Turkey hunting is a challenge; but waterfowl, requires proper scouting, setting up the enticing decoy spread with the right amount of decoys, calling the ducks within shooting range without spooking them. Bucket list: East coast swans and sea ducks with a muzzle loader.
