From what I understand the STW will out perform the Weatherby, but at what cost? How much of a performance difference is there? Estimated barrel life for each round? Recommended barrel length for each round? Cost / availability of brass and dies? I am looking to put together a 500 - 700 yard carry gun for medium game (deer, antelope, etc...). Lightweight, likely sporter barrel. Would either of these rounds be comfortable at the range with no brake? Also considering the 25-06, but I would like something a little "sexier" if it doesn't completely change what I'm after.
