I had the thought that if I ever got a WSM, it would be the 7mm. version, most likely, just because I have an aversion to the .270 for some reason. Availability (up here) of decent bullets might/could be the reason.
The 8mmWSM, what is it called?, the .325 WSM? yes - is also attractive, so to speak. The 8mm is more to my liking, overall. A .358 on that case might be even better for up here.
Good buddy Keith has one and it's a good shooter in a M70.
