Jim, I too live in Utah and have hunted for the past 40 years with a 270. I've always shot Nosler 150 grain Partitions and see no need to change. I load a near max amount of IMR 4350 and get accuracy in the <1" range. I've used that rifle/load for deer, antelope and elk and never had a problem or felt under gunned. Sell the 338 and put that money towards tags and reloading supplies.
