just so you know. the size/weight/muzzle velocity of a 30-06 and a 308 win is almost identical. but the 308 win uses less powder and is less punishing on your shoulder. i have rifles of both calibers and i prefer the 308 win because its just as effective while being a tamer round. the US military replaced the 30-06 shortly after WWII with the 308 win for this reason and the fact its lighter and soldiers could carry more. you should definatly consider this caliber if you need the equivalent stopping power of a 30-06.
