Well, obviously some disagree that the difference between the .308 to 3006 to .300 Win velocity difference is substantial in one but not the other. If one looks at my previous posts, I clearly stated COMPARABLE PRESSURES. The SAAMI specs for the .308 Win is 52,000 cup, the 300 Win is 54,000 cup, while the lowly 30-06 is 50,000 cup. If the 30-06 is loaded to 52,000 cup as the 308 Win is loaded, the velocity increase goes up accordingly. If the 30-06 is loaded to 54,000 cup then any velocity difference between it and the 300 Win decreases. If one can be loaded safely in the same model rifle and action, so can the other, so any major velocity advantage with the 300 Win decreases, while the 30-06 increases any velocity advantage between it and the .308 Win. If a .308 Win in someones opinion is almost as good as the 30-06, then the same must be said of the 30-06 as between it and the .300 Win Mag.
