I killed AK/Yukon moose/40yards, caribou/405years, mule deer/125yards, and dall sheep/250yards with a 30-06 and the 168 TTSX running 2930 last season. All of them died quick. The 150 TTSX will out penetrate anything out there. People telling him to shoot 180-220 grain bullets have never shot anyting with a barnes tsx/ttsx.
