I had a 6.5x55 Rem 700 and I was always frustrated be the lack of modern action reloading data, also I was never quite satisfied with the velocities I was able to get with 140's. My. 243 has worked like a charm this season, but I think If I get another rifle in that caliber range I'll probably opt for a 7mm-08.
As for the rifle choices, I have an extreme weather that I've had some accuracy problems with, although I think I'm getting those worked out. To be fair, this rifle was used, and my bought new featherweight has been an awesome rifle in every way.
All of that said, if I saw a finnlight and an extreme weather on the shelf for the same price, I'd snap up the finnlight, they are a beautiful rifle and are definitely on my rifle bucket list.
