lol G NOW ya tell us!
Sounds like you are doing MORE than your part (and setting a FINE example for your son I might add!). If your son is' nt going thru his pre-shot " checklist" then he has no one to blame but himself. I say work on that more and once he DOES gig one, he will become an outright " killin machine" . Sounds like he has mastered everything but actually drawin blood. Confidence is simply a result of succesful past experiences. The emphasis, urge or desire to " stick one" is weighing him down and causing him to forget all that practice. Just be sure and emphasize that to him when that deer is closing in for the last 20 yds!

Mmmmmmmm that which is impossible is ALWAYS within you, [:-]
