Name two common duty ammunition types and summarize their purposes.

Name two common duty ammunition types and summarize their purposes.

• A. Jacketed hollow point for training due to reliability; FMJ for duty use due to controlled expansion
• B. FMJ for training due to reliability; Jacketed hollow point for duty use due to controlled expansion
• C. Lead round for training; FMJ for duty due to penetration
• D. FMJ for training due to reliability; Jacketed hollow point for duty use due to expansion

Answer: (B)

Understanding why different bullet designs are used for training versus duty helps you see the logic behind the pairing. For training, you want reliability, affordability, and minimal fouling so practice is smooth and consistent across many rounds and firearms. Full metal jacket rounds deliver reliable feeding in most pistols, are cheaper to shoot, and produce less buildup, making them ideal for drills and qualification runs. For duty use, the goal shifts to stopping power with controlled performance. Jacketed hollow points expand on impact to create a larger wound channel and transfer energy to slow and stop a threat, while the jacket helps keep expansion predictable rather than letting the bullet fragment unpredictably. This combination reduces the chance of over-penetration in a real-world urban environment and provides effective, controllable performance. That's why this pairing is considered correct: FMJ for training because of reliability and cost, and jacketed hollow point for duty because of controlled expansion and stopping power.
