I tell you what to do,go and buy your self a Remington Modle 7 in 7mm-08
take the stock off it buy a 12 oz fiberglass stock from Summit(they make one for the Mdl 7),put a 1-6x38 mm scope on it and you have a ultra light that will handle elk out to 250-300 yds shooting 140 gr Trophy Bonded bear claws.
I have one and done the samething it weighs almost 5lbs on the nose.

Other option walk 10 miles and carry a Winchester M-70 in 300 WSM supper Black shadow,they only weigh about 7 with a full mag.
