Can you suggest me a 20ga O/U for upland birds, geese and ducks.

In my experience the 20 is not very friendly with steel shot in larger sizes and the max is no 2 steel and it leaves a lot to be desired for geese unless shooting is close over decoys. Other alternatives such as bismuth are very expensive.

I would not choose a 20 gauge O/U for Goose hunting, but it would serve minimally if you can decoy them close.
For upland birds and ducks, a 20 gauge would serve admirably.
Buy the gun that fits you. Buy a quality gun for a lifetime. In over/under guns at moderate prices, that means Browning or Beretta to me. Take the opportunity to try a number of guns before you buy.
I find most Trap, skeet or Fish and Game gun clubs have friendly guys willing to let you try their guns in the search for your special purchase.

I do 99% of my waterfowling from a layout blind and 99% of that is with an over/under. I do not find it a PITA at all. In fact I much prefer it over other actions as its easier to unload before exiting the blind and everyone hunting with me can see by the opened barrels it is in a non-firing mode.

Are you using a 12 or a 20? Whats your shotgun of choice?

OP... I like my doubles for clay games and the uplands but the Browning Maxus semi is for waterfowl;

What barrel do you have on your Maxus, 28in, 30in?
