so would you hunt deer with a bb gun? No...
would you hunt deer with a .22 short? No...
would you hunt deer with a .22 LR? No...
would you hunt deer with a .222/.223? No... (If you are ethical!)
-Why? Because it is not a deer cartridge! Therefore it should be used as it is intended as a GREAT varmint round.
would you hunt deer with a .243? Yes... (Because it is a deer cartridge tried and true!)

This too be continued... Aren't you guys sick of discussing the .223 as a deer cartridge?

By the way I think it is unethical to shoot with open sights unless you have shot enough to know you are a good shot. I ALWAYS hunt with a scope, because I don't trust myself. I know there are some out there whom are good enough, but more often than not the people around me that miss, miss because they have open sights. I will not let anyone hunt on my land with open sights.... Or hunt deer with a .223.
