Is this your son's first hunt? He may be an excellent shot at the range but, could perhaps get buckfever when he has his first shot? I shoot a 30.06 and would not trust a .243 as that is not my gun of choice. A walking buck is much different than a still broadshot target with any firearm. If he knows the gun and how he shoots.....perhaps talk with him about what his instincts would direct him to do ie: where to shoot, etc. Good mental practice is half of the battle. If he has good instincts and knows his firearm, he should have no problem hopefully.

Zrex, Until last year I thought neck shots were marginal at best, and actually they are NOT the shot for inexperienced shooters!! One must be very comfortable with how they shoot and what they shoot to make it very quick and clean. No Doubt About It.....JMHO.

My buck 8pt 2003 season afforded me a neck shot, his number was up pure and simple. One shot, one kill and he was down for the count. Lucky? I am not sure...What I am sure of is my shooting ablility, but just do not like a neck shot/moving shot unless I have an option that I am sure of.....and unless certain would never take a neck shot as there is way to much margin for error with inexperienced shooters/hunters. I prefer the boiler room for my shots, heart shots at that. Although a buck can run for a bit at times with a heart shot too. I have seen it happen one time, it boggled my mind. Go figure how they do it. What an exceptional instinct to survive Whitetails have........
