Which ammo type is stamped, dull in color?

• A. Armor piercing
• B. Frangible
• C. Ball
• D. Tracer

Answer: (B)

Frangible ammunition is designed to break apart when it hits, reducing penetration and ricochet during training. To help shooters quickly identify it, these rounds are often finished with a dull, non-reflective color and carry stamped markings that indicate their frangible construction. That combination—a stamped designation plus a dull finish—is what sets frangible ammo apart from the other types. Armor-piercing rounds usually have a darker appearance or distinctive color cues to show their hardened core; tracer rounds have a visible colored tip that glows in flight; standard ball rounds use a polished copper jacket and lack the dull finish and explicit stamping. So, the label “stamped and dull in color” points to frangible ammunition.
