Don’t let the cartridge names throw you; “7.63 Mauser”, “7.62 Tokarev”, “.32 ACP” (AKA 7.65 Browning) are just cartridge names rather than technical descriptions.
While the weight of the bullets used in commercial loadings of these three cartridges vary, all three cartridges use bullets of the same diameter. Ammunition manufactured in Europe uses bullets of .309 inch diameter; ammunition manufactured here in the USA uses bullets of .308 inch diameter.
Back when I was hand loading I used a great many .309, 85/86 grain bullets salvaged from .30 Tokarev cartridges. At present Hornady offers a .309 diameter, 90 grain, XTP bullet and Sierra offers a .308 diameter, 85 grain round nose bullet. Starline used to offer 7.62 Tokarev/7.63 Mauser virgin brass.
