270 WSM, .270 .308, 7mm Mag or 300 Win Mag in that order...have successfully deer (whitetail, mulley and blacktail) and elk hunted with all 4 calibers before.....the 270 and 270 WSM are by far my favorite rounds for deer/elk combo. Have also successfully used them both on caribou, moose, black bear and hogs. Happy hunting!
