A .270 is fine for elk if one uses correct bullets and puts that bullet where it will take an elk out. I would suggest a Winchester Fail Safe, X-bullet or a Nosler Partion. These bullets will work period. When Elmer Keith wrote we needed bigger caliber to do in elk, he was stating we needed better bullets. We have those now. One can find anyone of the bullets mentioned in factory ammunition. If you want to buy a new rifle, great, but you don't need one. Remember, 140 grain Fail Safe a 1/3 to half way up the shoulder and the elk will fall in 12 seconds.
