I'm planning on buying a new shotgun to use for turkey and duck hunting. I turkey hunt a lot more than duck hunt so I would say it would be used 80% for turkey hunting and 20% for duck hunting.
Heres an idea.
Why not just get an extra barrel?
Get what ever gun you want and get a long barrel for ducks.
And get a shorter barrel for turkey.
An extra barrel shouldn't cost to much.
Just an idea
