Thanks guys.
Yes my son has shot about everything out there, all my friends let him shoot at their stuff so he gets everything. Kind of funny I had him instructing the people who wanted to shoot the Barrett - he put 85 round through it that day by himself.
He has been going with me to that the last 5 years plus shooting with me quite often - we can shoot out to 100M in my front yard-, so it makes it nice since the ROs figure out pretty quick he is better than most adult at handling a weapon -good ass beatings will do that to them

As far as the Tannerite, the best part was it took him 2 shots, after the first he looked at the guys whose rifle it was and said " Your rifle is off!" LOL, "No, I told you it is 1" low and 1" to the left with the can on it!" as they are arguing everyone on the line is waiting - I edited that - . Then he shot it on the second shot and proceeded to blast 2 more before anyone else could. Not to be outdone, a guy "Donated 10#" , but he wanted to shoot it, so after 5 shot everyone wanted the "Kid" to shoot it, then he had a friend shoot it. LOL it was great!!!!
He can shoot!!!, I have been getting into long range shooting and he is right there with me, he has 3 out of 5 on a 16" x 24" @ 1362yrds w a .308 @ 175SMKs, I didn't try as I knew better.
