28 Nosler, 180g at 3150 or 168g at 3250 will get the job done in spades. Brux 5R, 8.5T, barrel, throated for 180g ELDM would be tops on my list to try, .796 BC. Second choice would be a 6.5/06 AI or 6.5 PRC with the 147g ELDM at 3150 fps. I would want a lot of energy dump inside the animal, thus the ELD-M.
