Looking to purchase a new rifle and I think I 've narrowed it down to one of these two calibers. I'm looking for a gun to shoot everything from TX whitetail to Elk with. Realistically 500 yds is probably the max I feel comfortable shooting at right now. I don't reload right now and I am worried about finding ammo for either one of these cartridges. I know they are both fairly flat shooting calibers, but would one do better against larger game? I've read a ton on both, but would like to hear from people that have actually used them in the field. Thank you in advance for any help you can provide.
