In areas that elk and deer are I use the same load. Hard to carry two rifles at the same time, and changing cases to a different bullet weight would be almost impossible at the time of hunting. It's also hard to retain what the bullet path is with different velocity when you getting ready to shot. If you have Nightforce scopes or on that line, and a range finder, you can dial it in. So I have kept my shots to a max of 500yds, which most rifle can reach without much problems. I generally use a 2 x 8 duplex Leupold scopes, and adjust my hold by elevating my rifle. I know my bullets path. Wind is a little more complex. Before range finders, I use my scope to determine the range. It worked accurately. I use rifles that achieve about the same velocities. The bullet path is about the same for 500 yards or less. So it's a no brainer in whatever rifle I use. Now I am having a wildcat rifle being built. I am looking to out to 700+yds. I will get a nightforce scope, and I already equipment to deal with temperatures, and wind because I am extending my range to shoot. It's not an elk rifle, but will work on deer, antelope, coyotes, and wolfs, I don't know if that helps or not, but that what I think.
