Pro-Line you might be different, or just a gun hunter. But believe me, a deer is not the toughest thing to take down. If he can't do the job with a 223, then he needs to stay in the house. I use all kinds of guns to take deer down, including 308, 270win, 12ga, muzzleloader, 44 mag pistol, and I feel very confident with all of them, and never worry too much about recovering them.

You said
Nearly 100% of the deer I've killed with my bow I could have killed with a 22lr to the brain.

I am really not understanding your point. You say they are easy to kill as the above statement, and then try to say they are hard and you shouldn't hunt with this caliber, yada, yada, etc.
