 A high-drag projectile is advantageous for two reasons; first, it reduces the impact velocity when fired against an earth or sand backstop, and second, it reduces the range if no backstop is used.Excessive range can be a very problematic when firing any large-caliber round; safety traces can often exceed the bylaw areas of the firing range, so range reduction is imperative.This is even more of a problem when high velocity, low drag rounds such as APDS or APFSDS are used.
