I'd go with the 03A3 if we're talking as issued and not "sporterized". The 30-06 offers a wide range of sporting ammo unlike most of the other military calibers. And the peep sights of the A3 are superior to the 03's sights. The 1917 would run a close second. It has a larger capacity, but we're talking hunting and not combat. Plus to me it's a little more bulky and doesn't handle as well. I do find the safety to be more user friendly than the A3's though.
