I lived in Quebec for 20 years and also moose hunted there. You don't say what your rifle is chambered in but from the choice of bullets i would say its a .30 of type likely an 06. I find that a 180 premium bullet will shoot just as flat as anything else out to 300 yds and pack a little more energy. I would not tinker with switching loads. Sight your rifle in with a premium 180 and you are good to hunt everything. I like a zero of + 2" at 100 yds for moose.
