[mp-gg] Re: The Uzi and further developments....
you are totally correct about silenced rounds but.....
Just to poke fun here....
what if you used a caseless round gun? No rounds on the floor. Or a
round catcher box on the side?
What about an electromagnetically acclerated round, no air?
Or more to reality, what about a gyrojet gun? (An experimental model run
of a few hundred machine gun gyrojet pistols was done. I held one at a
gun show. It was this cheap silvery "stamped sheet metal" looking thing
not like the black with real wound grips that you normally see in web or
in weapons books.) A gyrojet does not reach supersonic velocity until
down range. Of course it would be worth "nada" inside a room unless you
wanted to tickle everyone to death or maybe if you were taking out guys
in a gymnasium. But still it would be very quiet.
Then there is the "silent" shotgun shell from Nam that contains the gas
and shoves the wad and slugs out with a REAL rapid push from and
expanding aluminum bladder like an according in reverse mode, only real
fast. They had velocities of 650 ft/sec. (I think that is the number). I
think would be short range and sub sonic but it could kill you and it
would be real quiet and would work in a sawed off in a room
confrontation.
Any other quiet ideas?
