u should be able to get by for MONTHS on small game,dogs, cats, birds, fish, plants, so there is only a NEED to take ONE cow, or elk,moose, or bear a year, and maybe half a dozen deer. So much for the "need" of more than 223 for big game taking. 223 sp's take deer just FINE to 150m, even from short barrels. They also brain big critters just FINE, to 100m. If you can't get within 100m of ONE big animal a year, you are nothing but a LAME. ditto if you cant get within 50m of 5-6 deer a year, and that is range to brain deer with a subsonic .22lr.
