I'd have to go with my 1903 Springfield. Plenty accurate--I've put five rounds of GI ball ammunition into a hand sized group at 200 yards, off the bench. Substantial weight and a good steel buttplate.
Sling swivels in the right place to really get close and personal with a good leather 2 piece sling, and sights precise enough to hit a target out to 330 yards and beyond.
Plus, the capability to accept all varieties of what is possibly the most common caliber in the US.
I think it's ideal.
