I would not recommend a 270 wsm. They are not that efficient at all. You are very limited in releasing because most of the guns can't take a very long cartridge in the magazine. This limits your COAL and you will end up with every load being a compressed load, for the most part.
Does the caliber kill? Yes I have killed elk, pig, blacktail deer as well as mules. It just wouldn't be my first choice if I had it to do over again.
The 7mm-08, 308 or 30-06 AI would be my top three to choose from.
