Expanding Full Metal Jacket 124grs +P
The wetpack was realtively hard. It consisted of outdated law-textbooks soaked for six hours.
EMFJ worked better than expected. It expanded to 18mm (0,70") and stopped
after 11,5cm (4,52"). The accuracy of the expansion was impressive. The
bullet taken from the wetpack looked like a perfect computer simulation
of a how it should be. The wetpack showed an impressive shockwave with
a diameter of up to 6,5cm (2,55").
Fiocchi Semi Jacket Plastic Round Nose bullet did not deform at all. It
did wide superficial damage to the cover of the first book in the pack,
which I assume was due to the bullet's high muzzle-speed of 467m/s (1532fps).
Then it almost behaved like a Full Metal Jacket and penetrated the wetpack
14,5cm (5,7"). The last picture in the Fiocchi-Column shows the bullet
taken from the wetpack and an unused cartridge. The bullet taken from
the wetpack was perfectly intact.
Magtech Full Metal Jacked
My personal conclusion is, that the only bullet of the three tested likely satisfy in a defense situation is the Federal EMFJ.
