I have used the 180 gr Prohunter in a 30'06 and 300WSM on a couple elk and moose and many deer. Never any kind of failure and good accuracy. Those bullets that were recovered were all perfect mushrooms on the opposite the side hide.

Gamekings I have used always came apart - did not loose any animals but made me believe they would not penetrate as well if circumstances required it.

If you can't be a good example, may you at least serve as a dreadful warning
