From the Daily Inter Lake:
With a hip shot to the head, an elk hunter killed a mountain lion that was stalking him on Crane Mountain south of Bigfork on Sunday. . .

“I was using a cow call and I was bugling when I heard a twig snap behind me. . . . [A] little less than 10 [sic] behind me was a mountain lion, belly to the ground, crawling right toward me,” Smith said. “It was a pretty instantaneous response, it being that close and being in the attack position it was in.”

Smith fired once from the hip with his 7 mm magnum rifle, the bullet striking the mountain lion in the head and killing it._
