the MAJOR thing you need to remember is KINETIC energy; a .223 will only supply a limited amount of this energy at range;

go shoot your neighbor's cat with a bb gun, then shoot it with your .223;

go shoot an ELK with your .223 and he will run into the following month;

you want to 'humanly' kill your game; and not have to track it for that afore mentioned month;

you want to kill it outright if at all possible;

the bigger the game, the more energy is required;

the .223 was designed to 'injure',and not necessarily kill;

and was never developed as a hunting round; it was developed to
injure and maim humans;
