Is the 7.65 cal the same as 30cal or 380cal or 9mm?

There are a few different types of 7.65 cartridges, to include:

• 7.65x53 (this was used by Argentina in their Mausers and FN49 rifles)
• 7.65x25 Borchardt (this was used only in the Borchardt C-93 pistol)
• 7.65x21 Parabellum (this was used by Germany before the adoption of the 9mm Parabellum)
• 7.65x20 French Longue (used in Modele 1935 pistol and MAS-38 submachinegun)
• 7.65x17SR (this is also commonly known as the .32 ACP)

Bearing in mind that different countries and manufacturers throughout the years have had different standards of measurements for their bores, it would be considered to be in the .30 caliber range. Generally, cartridges ranging from 7.62mm to 7.7mm (such as the .303 British) are considered to be .30 caliber rifles.

The .380 ACP (also known as 9x17) and 9mm Parabellum (9x19) have a considerably larger bore than the 7.65.
