If you can't stop something with 5 rounds out of that gun, you best have the nearest B-52 squadron on speed dial.
I won't ask what you plan on shooting with it - probably the same answer I gave my father 20 years ago when I brought home a Marlin 1895 .45/70 lever action. He took one look at the size of the muzzle on it, and asked "WTH do you plan on hunting with that cannon?"
My answer was "Any damn thing I want to!"
