9mm Full Metal Jacket Ballistic Gel Test. Viable Option For Self-Defense?
This video provides an expert-level analysis of 9mm Full Metal Jacket (FMJ) ammunition for self-defense, featuring a ballistic gel test conducted by an experienced firearms enthusiast. The test evaluates Winchester 115gr and 124gr FMJ rounds fired from a Smith & Wesson M&P9 Shield EZ, measuring velocity and penetration depth. The findings highlight significant over-penetration risks, concluding that while FMJ can be a threat stopper, its use for self-defense requires extreme caution regarding backstop safety.
