Thanks for the ideas & thoughts here. I was raised with a strict "you eat what you kill" ethic so we'll stick with rabbits and tree squirrels. But we'll probably give him another year to grow & improve his aim a bit before signing him up for a hunter safety class. He has some impressive shots so far. At a recent 3D shoot, he nailed a heart shot on the flying goose (moving target) at 10 yards, spined the beaver at 10 yards & hit foam on the iron turkey at about 5 yards (obviously, I let the boys scoot closer to the targets). It's not consistent but it's still impressive.
I think that once he grows a bit more, he'll get closer to 20-25# at his draw and should have that much more practice under his belt.
Thanks again!
