Well, MSRedneck, I would like to hunt with my AR, just because I want to. One place I hunt has no shot over 100 yards and it is family land. I just don't want to break the law. Why do some people insist on posting to topics when they have nothing to add to the converstion?
If'n it was a nice buck, and you didn't want the head shot, I would think that with proper shot placement (easy at <100 yds) if you avoided the shoulder on entry, I would say a little high in the spine, or from an angle that hit the heart, or a good neck shot.....that the modern 223 hunting ammo should expand and kill very efficiently.
Would I preferentially use 223 over a larger caliber for a trophy buck, NO. But would I hunt with my AR,(especially for a close "easy" shot), YES. And a 2nd followup shot is a piece of cake with the AR compared to a bolt gun.
Of course the AR is available now in larger calibers too.....
If you keep it under 100 yards everythings cool as the .223 has enough foot pounds. From what I hear if you keep it over 1000 you can make a clean kill with the right shot placement. The .223 loses that right after 100 yds.
they have beat this into the ground on the other site.... there is no restriction on what you can deer hunt with on private land..22 cal. and up.....does not matter what you use just use good shot placement...some rounds just don't leave a blood trail, they bleed in side...especally with small calibers....I have seen this first hand.
