I use a .270 AI for elk, which is loaded to .270 Wby ballistics. The CT Ballistic Silvertips are a little too soft for elk hunting. Fine for deer and antelope, though. I would try the 140 Accubonds or130 Swift Sciroccos. I have used both of these bullets with success on elk - like the Scirocco better, but whichever one your gun will shoot the best. The 140 TBBC is also very good, as is the 150 Speer Grand Slam.
