Might it be fair to surmise the 06 at the time of WWI was pushing 2700-fps and the 300 at introduction a few short years later somewhere around 2600 to 2650-fps? If so then that's not a huge difference. Certainly not enough for a deer to tell the difference with a 150-grain bullet. That's the answer I've come too out of this discussion. So maybe Savage fudged the ballistics a bit, but perhaps not so much to be full on bologna. And certainly not in the spectrum of the 22HP tiger killer - but that's another story for another day.
Canada Rod and Gun Club, April 1922, about 7-8 months after the 300 Savage was introduced.
"The .300 Savage is loaded to equal the .30-1906-150-2700 service cartridge..."
Which was the most prevalent cartridge for the 30-06 that was available, with a ton of army surplus on the market. But there were other hotter 150gr loads, and heaver/hotter loads. They list a 150gr / 2900fps load. So the 300 Savage matched the prevalent 30-06 market loads.. but everybody knew it couldn't match what the 30-06 COULD be pushed to.
