I understand "New England Style Still Hunting" as tracking deer Benoit-esque in the snow. My favorite way to hunt anything including elk.
I once had a Model 7 308... if there is a single worse firearm than the old pencil barreled M7, I don't know what it might be. Stock heavy, barrel light. As poor a still-hunting rifle as I've ever owned.
The 308 Montana is my choice. I wish it had a heavier barrel, and when PacNor is back up and running it will go off to them to get a Factory dupe that ends .630" at the muzzle. However, it works as well as any right out of the box.
