we arn't talking match competitions here we are talking hunting situations. If you check your charts you will see a 30-06 and a 308 both compared with 150gr and 180grbullets that a 30-06 is actualy the flatter caliber. a 308 has always been the choice in competitions because it is naturaly a accurate caliber although ive seen quite a few 06's shoot right with a 308. in my opinion 06 has less drop more velocity more energy so it is the better caliber. On deer size game you wont notice a difference though!
