My wife asks me the same question along with why I need so many guns!!

I say different bullet sizes and trajectories for whatever you wish to hunt or shoot!

By way of repetition Big animals need big bores and the smaller ones less.By logic I did get the wife to agree that the best DG rifle would be a double vs a bolt.Now if I can just figure a way to use that same logic to tell her I MUST HAVE that engraved double 12 ga shotgun----
