How about 165gr. bullets for everything?
You can load a standard cup/core bullet for practice and deer, then load a premium such as the Barnes TSX for bear, moose or elk. There are also a lot of good factory loads, both premium and standard, in the 165gr. weight.
My Tikka -06 is capable of 1/2 in. groups with 165gr. Hornady SP, 57-58gr. H4350 powder and WLR primers.
