I would add the 10 guage 3 1/2 magnum and .300 Weatherby magnum to the list. When using steel shot on waterfowl I believe my Remington SP-10 magnum gives me an advantage I would not have with any 12 guage. I think the .300 WBY magnum is the class of the .300 magnums and I was very happy I was able to get one inthe well made and reasonably priced Weatherby Vanguard rifle.
