First thought is that a long range scope
(for shooting 800 - 1500 yds and a lightweight 8 pounds, all up, are a bit incompatible in my way of thinkin'.
From what I've seen lately a Win Mod 70 Featherweight in 270 Win or 280 Rem with a good scope would be a decent choice.
I've shot the 280 and was impressed. I shot with a fellow shooting an '06 in that model with a mid range priced scope that was good to 775 yards. Plus every thing would be well under 2k bucks plus you'd have the time to tune it a bit if needed.
Just a thought......
