I have owned both the 270 and 7 mm. The 7 mm is a joy to reload and is the best balanced of all the 7 mm imho, the brass is expensive. I know someone who used to hunt with a 300 wby, but only uses the 257 wby now for everything, as a point and shoot round. He uses either the 120 gr. partition or 100 gr. barnes TTSX, and it drops them its accurate too.
