What material did the military use for low-velocity rounds?

Explanation:
Low-velocity rounds are designed to deliver less energy and be safer for training, so the material choice focuses on something light and manageable rather than hard metal. Silk was used historically because it could be formed into a light, flexible layer around the projectile, which reduces overall velocity and energy without adding excessive cost or complexity. This made the rounds safer for practice while still providing a realistic handling feel and recoil. In contrast, rigid metals like steel or aluminum would tend to produce higher speeds and greater penetration, while rubber rounds are typically used in modern non-lethal applications with different delivery methods. Silk fits the historical approach to achieving a safer, lower-velocity round for training purposes.
