5.7x28 FN FMJ vs FN SS197 Ballistic Gel Review & Test
This video provides a detailed ballistic gelatin test comparing FN's 40-grain FMJ and 40-grain SS197 V-Max ammunition fired from a PSA Rock 57 pistol. The test evaluates projectile performance, including velocity, penetration, expansion, and tumbling, both in bare gelatin and after passing through a makeshift barrier. The presenter notes the tendency of 5.7x28mm FMJ to tumble and its impact on damage, contrasting it with the SS197's ballistic tip performance.
