FAQ

Why FMJ for training?

Low cost, reliable feeding, and reduced barrel fouling make FMJ ideal for high-volume practice. The consistent performance helps build shooting fundamentals.

FMJ for self-defense?

Not recommended. FMJ over-penetrates and doesn't expand, reducing stopping power and increasing risk of collateral damage. Use JHP for defense.
