The game kings are ok on deer but I'm not a big fan of them on larger game like moose or elk. I'd stick with a partition, accubond, trophy bonded bear claw, barnes x or something along those lines. Remember the weight of the bullet is also important. The optimum thing would be to have different weights for each type of game. For deer I like a little lighter weight because it shoots a little flatter and the bullet expands a little quicker. On bigger game you would of course want a heavier bullet.

But if you're looking for an all around round that'll do it all then I'd go with 180grs in a partition, accubond, throphy bonded bear claw, fail safe or barnes x. Just figure out which one shoots best (most accurate) out of your rifle.
