OK boys, I need your help, I am looking to build or buy a light rifle for back pack hunting Elk sized game out to say 600 or 700 yards. The rifle should weigh no more than 8.5lb loaded, including scope and mounts. The lighter the better!! I havce already decided on the scope. A NF NXS 2.5-10x32 with ultra light mounts and rail. I dont want a muzzle brake on this rifle either. The stock needs to be stable and rugged as my rifles get a pounding on these trips. Any ideas would be apreciated.
