I built a 280AI on a Savage LWH action 5 years ago. The LWH walnut stock is one of the lightest non-tupperware Savage stocks at around 26 to 28 oz. A 22” factory sporter barrel is going to be about 6 oz heavier than a Savage LW 20” barrel. I lucked into a new 23” SS FW barrel in 280AI (2 lbs, 2 oz). My pet 162 grain ELD-X loads provide velocities equal to those published on a box of 7mm RM Hornady Precision Hunter factory ammo. Harvested a nice WY mule deer at 325 yards any KY cow elk at 75 yards so far.
