I'm looking through my CTD catelog and I see this type of ammo that states it was banned by the geneva treaty or something like that because its so leathal. Looks like tiny little darts. Looks interesting if you had to use it for self defense or varmits close range. Has anyone actually used this and seen the results? CTD does not say how many are in a pack also and I was wondreing if this is just for 1 bullet? It say's limited quanities, so do the still make this or is it surplus?
