[QUOTE="TotoJuan, post: 1958511, member: 283"] Es interesante las conclusiones, armas de calibres màs "gruesos" y velocidades de proyectil màs bajas tiene mayor letalidad debajo del agua, Una 9mm disparada perpendicular a la superficie es letal hasta casi dos metros (7 pies) debajo del agua. El 7,62 del Garand a 2 pies (60 cm) ya deja de ser inevectivo, porque la bala se fragmenta al tocar el agua (por su alta velocidad, supondria).
