a .22 is the BEST all around cartridge? alright if we are going to be silly aout this I'll jump on the wagon. The .22 is not the best the .17 hmr is, it has all the advantages of the .22 and much better ballistics and penetration.
The small game arguement holds no weight in my book, I can shoot a rabbit or a squirrel in the head with a .30 cal and drop him right there, and have enough to eat. Or who saying I can't drop the powder charges through the floor and have a varmint killer. If some people think the small game arguement holds so much weight what if you are stranded on an island and there are no animals but insects? The .22 would be way over powered to shoot insects, you wouldn't have anything to eat!
