9mm Full Metal Jacket Ballistic Gel Test. Viable Option For Self-Defense?
This ballistic gel test evaluates 9mm Full Metal Jacket (FMJ) ammunition as a potential self-defense option, particularly during ammo shortages. While FMJ can act as a threat stopper, the test revealed significant over-penetration issues, with rounds exceeding 23 inches of penetration in gel and showing no expansion. The host emphasizes the critical need for a safe backstop due to this over-penetration risk.
