180 gr TTSX from a 300 WSM which hit and killed a large tundra grizzly, North of Nome Alaska in Sept 2008. Distance was 157 yds. Spine was hit. Bullet recovered under hide on off side. This actually was the 2nd hit, first hit going through and through just behind the shoulder. My best friend, the shooter, ran his Borden rifle action action so fast, making the follow up, 2nd shot, I never even heard the two reports. Just the one. I was watching via my Zeiss 15-45x60 spotting scope from across the draw and had better viewing than Jack Nicholson at a Lakers mid court floor seat. At the first shot, the bear, dropped straight down, doing a sort of "drop and roll" maneuver. Back on his feet a second later, only to be hit by the 2nd round which caused a DRT.
