non expanding bullets, Expanding bullets, and Frangible
They are lethal but the bullets don't kill, the people who fire them do.
it shoots a lot of bullets in a short time
37 mm pistols that fire rubber bullets
Smoothbore shotguns can fire less lethal projectiles, such as beanbags.
In forensics, geometry is used to evaluate evidence such as the trajectory of bullets, lethal blows and collisions.
Shotguns don't use bullets. Do you mean without a case or non lethal projectiles? If so, yes they have caseless ammunition.
It does not.
Frangible bulb do not need melting to set off the water
Ballistic gel simulates the effects of bullets when fired into human tissue. It can be used for testing more (or less) lethal munitions, as well as for ballistics testing and comparison.
guns&knives No, no no. Guns & knives are lethal. The idea of putting down a riot is to do it in a non-lethal way. Anti-riot equipment consists of tear gas, helmets, shields, clubs, and water cannon. Guns with rubber bullets are sometimes used; painful but non-lethal.
Frangible bullets are ones specifically designed to break apart into many pieces when they impact something. There are two purposes to this design:Creation of a large, but localized wound - that is, the bullet fragments cause a much larger wound at the site of impact than a normal bullet, but do NOT have the tendency to bounce around inside the target's body.Avoid the "through-and-through" possibility, where the bullet travels all the way through the target, exiting and continuing on, possibly hitting another target.Frangibles are typically used in close-quarter situations, since they have poorer ballistic characteristics than ordinary bullets (and, thus, a shorter range), and because they help avoid "collateral damage" due to #2 above. The point behind using a frangible is that the target should be dealt a severe, but localized, wound (putting it out of action) without endangering those nearby.
