I have shot every type and gauge of shot gun. The very few times I have hunted ducks over water I did use both pump and auto loaders and, in those cases the extra rounds did come in handy. I will add I was shooting when five rounds was still legal and we did load five rounds. But since I now only hunt upland birds and Dove, I find I no longer need the extra rounds. First off, finding a downed bird in the desert even with a dog is at times hard enough leave alone two and sometimes three. Just spotting where the birds, two or three went down is a challenge. I want to retrieve my downed birds and get back to hunting rather than looking for downed birds. The big advantage as I see it for pumps and autos is the ability to quickly pop in another round or two without breaking the gun. These are just my opinions, and you can disagree all you want but for me, two rounds is all I need. In my many years of hunting, 55+ I have shot many doubles and very few if any triples, so once again, I have no need for the extra round. I do own all three types of shot guns.
