I've been on a lightweight kick lately, but if you can get your rig to go 8lbs scoped, slung, and full of ammo, that will serve you incredibly well hunting the Western US, in my opinion. If I was going to put together a 280 AI to fit your requirements, it would look like this:
700 LA, ADL bottom
McM Classic Edge ADL
Hart #2 at 23"
Talleys
Leup 3.5-10x40 (I'd probably throw on an SWFA 3-9, but the Leup will do you fine...)
8 pounds is a great number for carrying and shooting. I find that I really have to concentrate when shooting flyweights, but I do love carrying them...
What bullets are you planning on shooting?
