if you currently own a 270 win, you have an adequate elk rifle imo. if you want a dedicated elk rifle, neither you nor the elk will be able to tell the difference between an 06' and a 7mmremmag in "killing power". throw a few to your shoulder and buy the one that feels the best. or you could practice some more with that 270 win, get her sighted in with 150 grain partitions, and kill every elk you see within 400 yards. good luck with your decision.
