Let's face it,even with good year-around conditioning backpack hunting is still all about weight. So lowering the weight of everything is important, including your rifle. That's why my .300 Win mag Browning A-Bolt stays home this year and my 6.5 Creedmoor Ruger Amer. Predator & 5- 15 x 42 SWFA scope goes with me into the mountains. But with an unlimited budget I'd want the following: 1. .300 WSM (or similar short magnum) 2. lightest 3-lug bolt action available, magazine fed 3. carbon fiber stock W/aluminum bedding block/pillars 4. Proof Research CF wrapped barrel and titanium muzzle brake (needed on a light rifle) 5. Vortex Viper HD AMG scope W/aluminum rings (Yeah, lighter quality scopes are available but this is my "wet dream" scope.) 6. MAGPUL nylon modular sling W/ flush cups OR... one could just go to Christensen Arms and buy all of this "off the rack" except it will have a 2 lug bolt. So... how about your UL mountain rifle, real or lusted after? Eric B.
