NO appreciable difference in any hunting situation. Either get an adult sized buttstock or just buy a small size slip-on Sims recoil pad. That will lengthen the stock to just about full size and it will make that gun so easy to shoot you or he would be able to go through 100-200 slugs a day at the range if you wanted to. If he does not like the feel of reduced recoil you could ALWAYS sell the small slip-on Sims pad here (I'd buy a used one in a heartbeat, let me know if you end up selling it, but I doubt you will!) or you could put it on any other gun it would fit, and it should fit all H&R's....<><.... :grin:
