This year will be my first waterfowl hunt. In the mean time, I am buying a 12ga shotgun specifically for steel (3" chamber) and I will work up some loads over the spring and summer. I'm in Upper Michigan right by (2,000 yards away) from Lake Superior and I will see more Canadian geese than ducks. Is there a good shot size that will work effectively on both? I plan to load a moderate 1 1/8 to 1 1/4oz load in a 12ga 3" shell to ~1400-1450fps for 35-40y shots at the longest.
Reading magazines I gather that BB is great for all around geese and #2 is great for all around ducks. What about a good for both shot size? Should I just buy a bag of each size from #2 to BB and pattern?
