Just putting a tray of ammo (9x19 reloads) away and a funny headstamp caught my eye. Well, its a fiocchi 9x18 MAK case! Now, what would happen if I were to fire this through a modern 9x19 pistol in good working order? I loaded it with a CCI SP primer, 4 grains of bullseye, and a montana gold 124 grain JHP. Obviously the bullet was seated out to the same depth as 9mm. Im obviously going to go pokin around now but assuming worst case scenario, what would happen if this was fired in a 9x19 pistol? Would I even notice? Or would I notice when the gun explodes violently in my hands....?
