The 10ga came into it's own when steel was mandated, in that you have a greater payload, and is, IMHO, making the 12ga 3 1/2" obsolete before it became popular.
I have friends that are using the 10 for all, except chickens, thir hunting needs, from geese to ground hogs and pigeons.
There is quite a selection of shot availible for the 10 now.
