It is often quoted here that the 30-30 has killed more game than any other cartridge. Invariably, the next post states the 30-30 has wounded and lost more game than any other cartridge. My manuals show you can attain similar energies from the 30-30 and .22. However, the .22 cal has 1/3 the weight. I' d take weight over energy anytime. If you want to add a higher level of skill, learn to hunt with a bow, you get a longer season to boot. Why take the chance of losing animals with a woefully underpowered (and illegal in many states) cartridge when so many better choices are available?
