Any one shoot a 307 win contender?
Yeah, I shoot it because I like a rim on it for easier extraction. Ballistics are right there with the .308Winchester. I also shoot the .356Winchester and have a barrel for the .348Winchester. Brass isn't that hard to find over the internet. All are fine for elk sized game +.

However, this is in the Encore that can take the pressure of these rounds. A good .30caliber for the Contender is the .309JDJ or .300Savage.
