I would have to agree.
the only thing I could think of would be a frangible round, shot against body armor except the frangible round is laced with mustard gas or something to that effect.
then again I don't know how much gas you could get into a small round like that and if it would be lethal.
either way, bullets have been doing a good job for hundreds of years, the only thing I would want improvement on is unlimited ammo[Beer]
