We grew up learning that turkey was to be cooked for at least 15 to 20 minutes (longer for much larger birds) at higher temp (400 to 425F) to bring it up out of the "danger zone" faster as well as "set" the skin (to prevent the skin from going soggy or soft as well as prevent skin splitting), then reduced the heat to cook lower (325 to 350 F) and slower to avoid overly dry meat. Altitude also matters!
