Do you think that the 30-30,30-06, and 308 are the only cartridges available? Yes, I can name several rounds specifically designed to hunt deer size game. 25-06,260,270,280,7mm-08, various 7 mags, etc..... Taking a 4 MOA rifle to the field was not my point. I was talking about missing by unforseen circumstances, not because your rifle is incapable of shooting any better. For instance, what if the deer moves between the time you think you are in the perfect spot and the gun actually goes off? I am going to assume you have been hunting for a while? Have you ever not hit exactly where you aimed? Have you ever missed anything you have shot at? I would be shocked if you say no. I can tell you that I have been hunting for a lot of years and have taken more deer than I can count, and not all of my shots have been exactly where I wanted them. I take comfort in the fact that I am using a caliber large enough, that, God forbid, something goes wrong, has enough power and energy to either do the job or anchor the animal until I can correct my mistake, not leave him running around to die a slow and painful death. I am not going to debate the fact that the .223 will kill a deer, it will. So will the .22LR. Is it a good choice for deer, my opinion is no.
