.308 Winchester is still a great caliber. You can compare the numbers against the 30-06 here - they arent too much different:
.308 (or 7.62X51 NATO) is still used by the military and is preferred by snipers.
Watch any ammo you may buy online. There is also a 7.62X39 which is different and will not work in the Winchester bore.
