Frequently Asked Questions

What are the main physical differences between 7.62 NATO and 7.62x54R cartridges?

The primary physical difference is that 7.62x54R is a rimmed cartridge, a design from the late 19th century. In contrast, 7.62 NATO is a rimless cartridge with a rebated rim, designed for more reliable extraction in modern firearm actions.
