My choice would be a Winchester M 70 Featherweight .30/06. A Leupold 6x or 2-7x would be good choices for scopes.
Load it with 180 grain Nosler Partitions and go hunting.
Good choice, and one I had for a long time, but the OP want's a lightweight... the M70 isn't!
I feel like one of those featherweights in a LW stock like an EDGE or Brown, is just about right. for me its like the 3 bears, Standard featherweight too heavy, 308 Montana too light for me to shoot really well in all positions, but a 22" featherweight with a 22oz stock just right.
