I would go a different route altogether, you have the light cartridges well covered already... the 16.5" barrel shortens it a bit but really doesn't shave a whole lot of weight... how about filling and entirely different niche altogether... a 16.5" medium bore, I would go with a .358 Win... I happen to have a Ruger M77 Mark II Frontier in .358 Win with a 16.5" barrel and can speak to it's efficiency and accuracy, most of my big game animals over the past couple years have been taken with this rifle from 20 yards to 250 yards... additionally I shot two coyotes while deer hunting using 200 SP's with remarkably little damage, small hole in and small hole out... at least it is worth consideration... it is like wielding the Hammer of Thor, on everything from coyotes to moose.
