Although the 30-30 has probably killed every north american big animal around, it still would be wise to take the model 700. I have killed at 130+ yards with mine but ive used it for years and really know my gun. I would totally hate myself if i took my old lever up to canada and had to empty a tube into a huge whitetail cause he wouldnt go down. The hunters in the late 1800's had to use the little 30-30 cause there werent alot of choices in smokeless powder rounds, but i bet if they were around today going after northern big game they'd be packing magnums. I love my 30-30 but have witnessed to many whitetails in my area take several rounds to drop em, so i can imagine the monster bucks in canada.
