7.63 Mauser vs 7.62 Tokarov

[Johnny Peppers]

Hope this doesn't stray too much from the original posting, but back when there were several ammo companies loading the 7.63mm Mauser round, the bullet diameters varied from company to company. In the 86 grain FMJ bullet Western used a .3088, Winchester a .3105, Remington a .309, and USCCo. a .3105.
