I've never hunted with a hunting rifle setup over 8lbs, at least that I am aware of...
I am planning on building/setting up some kind of 6.5 with a KGB Bravo or some kind of similar style stock (this place is a bad influence already lol), I am guessing its going to land somewhere in the 9-10LB range when done(no bipod).
I am a little concerned about weight, as my elk hunting is primarily thick/dark timber hunting, carry the gun in hand, short range, quick shots.
However, I have no love for recoil, and I plan on this being my everything gun for now, and my deer hunting usually is more open country.
I think I am willing to pack the extra weight for shooting a more forgiving system, and one that i can get adjust to better fit.
