I live in Texas. But I use my .223 to hunt deer and hog here in Central Texas. I killed a nine-point buck that dressed out at 175 easy. Now, I will say this, I believe shot placement is important. Bullet choice for this caliber is important too. I grew up with an uncle who killed deer and hog with a .222 bolt-action. Yall can think what you want whoever reads this, makes me no difference because I ate good. My advice is take a look at where you live and think about it. In Texas, we have no indigenous elk or bear where I hunt 99.9 percent of the time. So I shoot my .223 every year. And my tummy stays full and so does my freezer. Also, I've seen dumb_ss hunters who couldn't hit the top of a lake if they were shootin from the bottom up with a .243, 30-06, .270, or an elephant gun. Bottomline is whatever you shoot with, practice a lot, and consider your region. Heck, if it's that big of a decision buy the .223 and order yourself a .243 barrel
