My 6 yr old boy so wants to go Turkey hunting as well. Took him to the shooting range and the noise didn't bother him (had good ear protection on), took him to sit in a ground blind while friends drove our woods (Already had knocked down 3 bucks and a doe opening day) and he handle the sitting very well. He was so proud that the shooting was one of the guys getting a nice doe. I told him if he continues being very responsible I would take him to sit and call turkeys, but not while I have a gun. Legal age here is 10 as a mentor which they just started and plenty of things to shoot till then. I'm worried hearing a 3.5 turkey load in a ground blind might scare him silly! Miss the old Pigeons for target practice long killed them all of at the farm. Biggest thing I would worry about is too much gun too quick. BB/Pellet guns, then .22... Biggest concern is closing eyes before pulling the trigger anticipation of the kick. At the end of the day you know your kids better then any of us, and what the comfort level is.
