ridge running rifles
I've hunted a bit in the blue ridge country of N. VA and PA and hiked quite a bit of same in NC and TN. One thing to keep in mind is portability. There are plenty of steep, rock strewn, laurel choked areas and a shorter lighter, rifle will have its advantages.
The win/marlin are tops in that department. The marlins are easier to maintain/clean, and scope easier than many of the Wins out there.
You may not be satisfied w/ 30-30 power, though its plenty for what you are going to do. Thus the .308 BLR might be a good compromise.
I'm thinking a full length 7600 is too much rifle to tote up and down all day. A carbine version might be interesting , especially on running hogs in front of dogs. But it will be heavier than the BLR or a Winlin.
That is pretty country, I've trout fished in Unicoi county for years.
