Ah, I don't do much hunting but a rifle for waterfowl isn't the best thing. If you want to go deer hunting get the Remington 770 which is the .270. I've shot it before and I could show you some pictures if I can find them of the entry/exit with a deer.
I guess technically I could hunt with my AR-15 because the scope I've got coming will shoot decent up to about 400 yards.
