Moose......elk, bear, buff.....I'm sure either would work the same on any of them.
Actually, my 6.5x55 is one of my favorite hunting rifles, and it seems perfect for caribou. Admittedly, I have shot less than two dozen caribou with it, a lot less than I've killed with either the 6mm or the 7mm-08. But the difference between the latter two when used on caribou has been readily apparent to me in terms of which has been able to more quickly put them on the ground.
I do not have disdain for the 6.5X55 at all. However, if it were every bit as effective as the 30-06 then it would make no sense to use a 375 or 338 when the 30-06 was just as good; it would further make no sense to use the 30-06 because one could just as easily use a 6.5. That argument might work on deer or hogs, perhaps even elk. But when you get to animals that easily top 1000 pounds, I'll put my money - though I know they all work- on something bigger being better than the 223, 243, 6.5X55, 7mm-08, 30-30, etc.
