I just got back from an elk hunt with my first experience with the tipped gameking "gamechanger." Using the 165gr in my short barreled 7 saum, pushing them about 2965fps. Shot my cow at 462yd through the shoulder, and recovered it just under the offside hide. She stumbled around for a few seconds and went down. Good penetration, quick kill, held together well, shoot well, not much not to like so far. But would like to kill something up close to get a better overall feeling. Retained weight was 118 grain, very accubond-ish results which is exactly what I was hoping for. Been a long time fan of the accubond but wanted to give these a try with the much higher bc. The gamechanger is definitely the best "high bc cup and core" bullet I have tried so far.
