I've got a 20 inch Satern barrel with a 1:8.5 twist. I've shot from 90 grain to 130 grain bullets with no problem. I haven't shot in extreme cold weather, most of my shooting is at about 200 feet above sea level.
There are quite a few vendors for uppers. Call or e-mail Bob at Templar Consulting, he sells Grendel barrels with progressive rifling and can probably answer a lot of questions.
He can build you a barrel, or upper, too, if you like.
