In Minnesota the smallest cal, you can use for Deer is the .24�s. This is the first year we can use the .30 carbine. So the .223 are not a Deer round in Mn, no matter what you might say. If you don�t think so, come to Mn and try to shoot a Deer. I am sure that you will find some people around here that will disagree with your ideas of the .223�s as Deer rounds. They are called the DNR.
That said;
This year while Deer hunting, a fellow hunter shot a 8 point (or 4 point if your from out west) with a .243win the shot entered the back strap � the way back. The bullet ran up the back strap not hitting bone all the way up and stopped in the neck just short of the blood supply to the brain. The deer could no longer run fast but it was not stopping ether. Another hunter down range with a .25cal placed a shot under it�s ear when it stopped to go down a collie.
If the first hunter would have been using, lets say a .308 with 150gr bullet a second shot would not have been necessary.
If the second hunter would have been using a .22RF, the deer would have dropped just as hard.
Placement and Penetration.
