I guess when I think of diverse, I'm thinking of a wider range of choices than you.
Most of the rifle bullet offerings are 185 grain to 300 grain, but most folks stick to something around 240 grains. 30-06 goes 110 to 220 grains in general offerings.
A 125 grain bullet in a 30-06 is a very viable groundhog round. At the top end you can take a moose.
You mentioned deer and hog. Both are pretty much in the same class of game as far as I'm concerned. At least on my gun rack, there is no difference between my hog rifles and and my deer rifles. Now I'm sure somebody is going to say they've taken Moose with a 44 Mag, but it wouldn't be my first choice.
I cant see what would be wrong with shooting Moose with a 44 mag? I've hunted Moose with a couple different 44's but never an opportunity to kill. I was there when a friend killed one with his Marlin 1894 and it worked great.
