In the hands of a skilled marksman, with the right bullet, and given the perfect shot at close range, the 223 will cleanly kill deer. From what I understand, the 223 is quite popular in the south for shooting the small whitetailed deer found there. Keep in mind that these deer typically weigh in at around 100-150 pounds, and their chest cavities are around 8-10" in width. A mature mule deer buck will be 2-3 times as big. I feel that the 243 Win. with 100 grain bullets is the smallest caliber that I would use, if the range is kept under 250 yards. That is why my 243 is now a pure varmint rifle, and my 270 Win. goes deer hunting with me.huntducksordietrying said:
If you are good enough to put that little 50 grain slug in the deers brain its yours. Guaranteed. Otherwise forget it. It is not a good deer rifle. The little slugs may not get through a shoulder and the deer runs off wounded.
I killed my first deer with .222. I was in the 5th grade, living in Texas. The deer dropped like he was slammed to the dirt by hulk hogan, but it laid there bleating. The adult I was hunting with had to dispatch the animal (I couldn't do it).huntducksordietrying said:
