The ideal handgun bullet would expand to the greatest diameter that is possible for the bullet to still penetrate 12 inches of gelatin, correct?
Since the military can't use expanding bullets, why not get a FMJ bullet that is so light it only penetrates 12-13 inches, but shoot it at blazing fast speeds to cause as much damage as possible? I know that 1200fps is pretty fast, but if you used, say, a 70 grain FMJ, I'd think that would do more damage, just due to the speed and possibly even fragmentation.
How fast would a 70 grain FMJ go from a 9mm +P+? I know the 115 grain bullets can get up to nearly 1400 fps from some of the hotter +P loads out there, so maybe what, 2000 fps?
Think that idea has any merit?
