I would select one of these for hunting elk and moose: 300WSM, 325WSM, 338, 30-06. I like to have plenty of powerand these will do just fine.The 270 will get the job done but I wouldfeel alittle better going a step up.I believe the 06 and 300wsmare the best "all-around" calibers to hunt everything in North America maybe with the exception of Grizz or Brownies.
