Rule 303
AH elite
Rock Rat, a 250 grain 375 projectile should get the job done. I say should. I have not hunted any of the animals you are after-intended to- however I would test the projectile on some home grown elk or at least deer first. I have found that standard cup & core bullets to work fine on light game. However will they stand up to an angling shot from the rear or front? I can't answer that as I do not know. My advice for what its worth. If you set set on using the Game King, by all means do but make sure the subsequent rounds are loaded with a premium bullet like Woodleigh, A Frame etc incase you need to shoot at the south end of a north bound animal.
