I have never been in a hunting situation where I couldn't stalk to within 200 yards of any animal...
Then you haven't hunted enough. I haven't taken that many elk - let's say less than 10. My last one was shot at a bit less than 300 yards, and that's as close as I could get. It was above me on a grass covered slope, and the bush and log I used to conceal myself was the last hiding opportunity between the animal and I.
I took it with one shot from a 30-06, with a 165-gr. Interbond, by the way. If I had had a 260 with a suitable 120 - 140 gr. bullet, I'm confident that the results would have been the same.
