Not part of the OP's question. BTW, The .30-06 would have been extinct if MacArthur had not pushed for the M1 Garand to be re-chambered to it. It was designed as a 10 round .276 Pederson.
The 7mm08 was an attempt to make a U.S. cartridge that had the characteristics of a 7x57, the .276 is 7x51, same as the 7mm-08. The U.S. market had and still has an issue w/ everything metric. 6 of one, 1/2 a dozen of another. They both do the job. I doubt any game would tell the difference.
