Hope you can load it insanely fast!
I have a buddy that goose hunts with his rarely. It does the trick but would rather have his 12 ga with all the shooting. Sitting beside him shooting my SBEII with 3.5 #4, we were both dropping birds all morning. Saw no gain of the 10 over the 12. If you like it, shoot it. Just be sure to get really good at shooting it. You're not going to want to shoot it all morning, plus having the single shot on waterfowl is going to frustrate you a little bit.
