Good Googly-Moogly! Not surprised to see so many recommendations for 30-cal. magnums, and the like. Am quite surprised that not one recommendation was offered for the 270 Winchester! Given the modest parameters, the 270 will do everything required, in a light or standard weight package, without a brake, and without breaking the bank. Plus, a good selection of ammo can be found on the shelf of most any retailer, for a modest price. Some thought can be given as to bullet weight, so as to tailor a load for a given species...on the heavier end preferred for Elk. Or, had antelope not been entered into the equation, I might offer a straight .30-06, as has already been suggested. Either one would be a successful, go-anywhere, do-anything choice.
