When have you ever shot over 3 rounds at an animal? Not saying you haven't I've just never understood needing more then 1 follow up shot at most. Im talking big game not yotes and such.

The 270WSM is IMO a lot better if you reload and short actions are usually more accurate then the longer actions rounds. Not always but for the most part.

A 270win is much more popular then the 270WSM but the WSM has only been out a few years so its hard to really compare them. The 270 with a 130 grain bullet is prob the best combo for whitetails you'll find. And since the WSM is a bit faster is also a bit flatter with the same combo.

The WSM's are the most popular sellers in the last4 years or so but mainly the 300 and 270WSM's. Nothing wrong with the 7mm it just hasnt caught on as easy.
