I've used 150 grain partitions on elk and 120 grain B-tips are tough to beat for antelope in the 7-08. I had to finish a big desert bull one year that had been shot several times with a 338 WM, for that i had a 7x57 on hand with 175 grain SP. IMHO you can't go wrong with the medium volume 7's for elk or any ungulate for that matter.
