Which training round is described as case mouth closed with a rosette clamp and a violet tip?

• A. M199
• B. M200
• C. Blank Round
• D. Dummy Round

Answer: (B)

Training rounds are identified by distinctive construction features and color markings to prevent any confusion with live ammunition. A violet (purple) tip signals an inert or training round, not a live projectile. The description that the case mouth is closed with a rosette clamp describes a specific way the round is sealed and secured for training use, ensuring no propellant or firing capability is present. When you see these exact cues—case mouth closed with a rosette clamp and a violet tip—the round is the M200. Other training rounds will typically use different color indicators or different sealing methods, so they don’t match this particular combination.
