RE: Ethical Calibers for Deer
The "ethical/unethical" debate is getting old and is just an excuse to stir up crap and belittle fellow hunters on message boards.
It is a fact that not all hunters can make head and neck shots, so a small caliber (ie 22-250, 223) would not be a good idea for deer hunting. On the other hand, I have known some guys that only made clean kills on about every third or fourth deer they shot at with a 300 WM because they were scared of the gun.
What is good for the goose may not be good for the gander. If a hunter shoots a rifle in a caliber he is comfortable with he will more than likely practice more and be more competent with it.
I DO NOT advocate head/neck shots, but if a hunter knows his gun and can shoot it accurately, there is no reason why a head/neck shot would not be "ethical". I like a nice bang/flop.
