My answer to weight was a Brown Precision pounder stock and no bottom metal. I also speced all the graphite fiber in the forearm that was possible for stiffness.

By doing that I could go up to a #4 Lilja barrel for stiffness and Leupold 6x36 LR. All up weight is 7.5 lb with a nylon sling and no ammo. Shoots 175 gr Sierra at 3075 into .75" 5 shot groups. Zero 3" high 100, on at 290.
