What is inside a 7.62x39?
This video compares Russian 7.62x39mm ammunition (mistakenly referred to as 556 in parts of the transcript) with NATO 5.56x45mm. Key differences highlighted include the casing material (steel vs. brass), powder morphology (spaghetti-like strands vs. spherical flakes), and primer systems (Berdan vs. Boxer). The Berdan primer system, common in Russian ammunition, features two flash holes, while the Boxer primer system has a single flash hole.
