That being said, over the last 100 years to the present, what has led to the developement of so many new whiz bang calibers?
While the 30-06 does do many things quite well,there are many cartridges that do offer advantages in manysituations.For instance the 25-06 will kill any deer that the 30-06 will with a flatter trajectory and less recoil.The 300 wsm and 300wm do shoot flatter and can be an advantage for hunting larger game.The 338win mag is certainly a better choice for grizzly and brown bear.
