I have a friend in western Montana who used to always shoot 300 WM and 180gn bullets for elk. Now that he is older (and weaker) like me, he has progressed to the 6.5 CM and 131gn Hammers, and has taken 2 huge elk bulls in the past 2 years with no issues, one at 370yds, the other at 490yds. He loves this rifle combo.
Great info, thx for chiming in
