My 12 year old did really well with the Weatherby .308 but the next boy down isn't as strong with firearms. With that in mind I have been looking at various calibers to get him so the recoil doesn't scare him. From everything I have read the .243 is the average caliber for new young deer hunters. I realize I could let him shoot a .223 but it would need to be a "better placed" shot versus a something that might be a bit forgiving on a "not-so well placed" shot. Other calibers I have been looking at are the 25-06, 257 Roberts, and 6mm. It is a pretty easy decision for the .243 since I could drive down the road right now and grab a Ruger American for $300. Between the American, Axis, X7, 770, and the ATR I figured the Ruger was a better buy.
