I'd recommend a Howa 1500 or a Weatherby Vanguard in the caliber range starting at 6.5mm Creedmoor and ending with the 300 Winchester magnum. My personal preference would be the 30-06 Springfield, but anything in that range will work. For optics I would recommend a Burris 3-9x40 Full Field II. That setup will serve him well as long as he wants to hunt.
