Well, I use a 338-06AI. It's based on a Rem 700 mated with a Gaillard barrel. Boyd's laminate and IOR 6X. The rifle is not a light weight. It comes in at around 10lbs. A little on the heavy side but a pleasure to shoot. We usually cover between 2-6 miles per day. I'm 6'4" 230lbs so it doesn't much bother me. Some it might. For mountain hunting not.
