Croz2173: 7m/m Remington Magnum with 160 grain Nosler Partitions for Black Bear, Mt. Goat, Elk, Bighorn Sheep, Caribou and the occasional marauding Griz!
Then down load to the 140 grainers for Mule Deer, Antelope and Whitetail Deer.
All around gun/cartridge - situation solved.
Second choice would be the wonderful and very masculine 270 Winchester with appropriate bullet loadings.
Good luck with whichever you choose.
Hold into the wind
