If you want a really light rifle, I always recommend sticking to a cartridge that won't beat you up too. Either 7mm-08 or 260Rem are easy shooters with pretty good down range performance. A Kimber 84 Montana weighs 5lbs 3 oz in 7mm - 08, or 260 Rem. but these are both pleasant cartridges to shoot in this light a rifle. Retail on the rifle is pretty close to the Rem700 Mountain/lightweight guns too.
