RE: Which gun should I give to a 15 year old?
Sorry about your loss as well visitor. Congrats on the grandchild making it to an age and being ready for the woods as well! I too will say let him use the .308. It is MUCH more practical and useful than a 30/30 and is' nt anything that really will need ever to be replaced for hunting in other areas or for larger game!
Good luck and keep em in the woods!
