My good friend uses nothing but a Browning BLR 308 and 150 Corlokts. He has killed some nice bulls out around 350yds, but mostly he kills smaller/younger bulls & cows up on the ridges in mixed timber and under 200yds. I like more "oomph" in an elk round but there are many who use the 7mm08 and do well. Big bull hunts though, that cost a lot of money? Its marginal.
