Here's how the text of the Leverbolt's "Special Notice" starts: "Mr. Newton has long been known to riflemen, first as the designer of high power cartridges such as the Savage line of .22 high Power, 250,3000, and .300 Savage, later the .256 Newton, .30 Newton, and .35 Newton..."
Could Newton have designed the cartridge during the heyday of the .22HP and .250-3000 and presented it to Savage who in turn slept on it for a few years?
