The one you are most comfortable with and shoot the best. Whichever one you take paractice twice as much as you think needed.....the. Practice some more. Shot placement is critical! Have a great hunt! By the way the 416 will do everything you want provided you shoot it well. A 416 solid on small plains game is very effective placed properly.
my model 70 featherweight 300 wsm with 180 grain accubonds has been 1 shot lethal on large plains game . I really enjoy the feel of the gun
