My old friend is joining me in my home state of Wyoming for an elk hunt.I have grown up with a Remington 700 in a 30-06 that has harvested many animals over the years. My whitetail hunting friend loves his Marlin ,lever 30-30, is this rifle appropriate for elk? in what grain? I have received a variety of local responses and would like to put this question to the hunting public. My first reaction was to tell my friend to buy a new rifle .270 and up, but I would like to hear from others. Thanks
