I don't think you will be upgrading from the 7mm Rem Mag with a 6.5 or 7 PRC for the ranges you are talking about. However, if you want something different either 6.5 or 7 PRCs will work ok, too. Considering the brake and/or suppressor, why not step up to the 300 PRC? I'm assuming you are wanting a PRC.
