That's a common misconception, as Scorch pointed out and Metal God originally mentioned. 7.62x51mm was originally based on a "stretched" .300 Savage case.
Lengthening a cartridge doesn't really fit with the general pattern of cartridge evolution, but we have to have some oddities and exceptions. (Like .35 Whelen actually being based on .30-03, not .30-06 as is commonly believed.)
