Originally, the lovely little 300 Savage almost matched the velocity of the then-standard .30-06 load with a 150-grain bullet. The ought six soon was pushed well beyond its first specs, however. If you only compare today's numbers, the 300 isn't as close. Back when, they were.
But even then, the claims for the 300 were mostly to sell the Model 99 rifle. One might make the same observations about advertising exaggeration with regard to the 308, the 284, and several recent introductions: they almost match bigger and highly popular cartridges.
