Greenbridge....you have chosen a very good way of putting a Elk to sleep real quickly. as long as you can shoot well and your gun fits you good. I stick by my loads I have used over the many years I have hunted, they have never failed me so why should I change, I shoot a 340 Weatherby, which is almost the same thing and for Elk I have done real good with the 210 Nosler Partition. I even shot a sage rat with it once at 50 yards, oh well, boys will be boys. Have fun with your new rifle my friend...
