There is an obscure reference to Charles Newton having designed the .300 Savage. I have seen it in a circular enticing investors in the Leverbolt Rifle Co of about 1927. Anyway, I saw this in black and white and there is no mistaking it. iIused to collect Newton rifles and had most of the catalogs and nearly all of the paper stuff his companies put out from 1914- to the end in the late 1920s. The first time I ran into this little nugget of cartridge history, I had to wonder if I was the only guy to have ever noticed this.
