The 7mmremmag is certainly a fine choice as an all around cartridge.You can use 140gr to 160gr bullets for game ranging from pronghorn to moose as long as you choose your bullets wisely.There is really no need for heavier bullets for these animals.There is absolutely nothing other than the largest bears that I would not hunt with the 7mmremmag.For the largest bears,I would want at least a .338win mag or perhaps even more.Good luck and good hunting.
