Not sure what you are looking at but my Nosler #6 manual shows the 06 faster at every bullet weight. In fact according to Nosler the 06 will push a 168 grain bullet faster than the 308 can push a 150 grain bullet. Those numbers take into accound the different operating pressures of the 308 and 06.

Looking at one manual often can be misleading because it shows such a limited view of the powders available at that burn rate.

Real world velocity differences are even greater than the manuals show because the 06 and 308 show the same classic pressure signs at the same operating pressure on average.

I think everyone should own both..the are both wonderful calibers..the 06 has tons of data available, and a proven track record as does the 308...i reload,shoot, and hunt with both, and neither has let me down if i do my part...it all comes down to personal preference...that being said, do your homework here on the internet...there is a prolific 30-06 hater running rampant on a few forums out here..comparing modern 308 data to pre WW2 30-06 data, claiming the 308 is so much better...if you see this guy..do us all a favor and kick him in the nuts...

.308 is a short action and can fit into a lighter handier rifle, -06 is about 200 fps faster when both are loaded to max with identical bullet
