went to the gun show and found a tale with non lethal, less lethal, and full lethality rounds. all 12 GA. the full lethal ones are nasty. flame throwers, ball mace, ( not pepper spray kind of mace), razor type shredders, tracer slugs, door breeching rounds... then some less lethal ones like these cubes that dont penetrate walls. maybe the saying goes here, if you have to ask... well they sold em there, so they must be but it makes me wonder, cause i would like to buy a lot of these. anyone know?
