In answer to your question. Why not big bores? I am the guy who likes to shoot prairie dogs with a .375 H&H. Season 2002 I took a little mule deer buck with the .375. It flat knocked him off his feet. He went MAYBE 120 lbs. on the hoof. I have killed deer & antelope deader than yesterday's puppy love with a .243. For me it is what ever stikes my fancy at the time. I am blessed t o be able to use just about anything I want. Last season I took my deer & antelope with an old .30-30.
