Trace Bullets Settlement For Free

The NIST Ballistics Toolmark Research Database (NBTRD) is an open-access research database of bullet and cartridge case toolmark data. The development of the database is sponsored by the U.S. Department of Justice's National Institute of Justice.

By examining unique striations impressed into a bullet from the barrel of a gun, expended ammunition can be linked back to a specific weapon. These striations are due to the rifling inside the barrels of firearms. Rifling spins the bullet when it is fired out of the barrel to improve precision.

?We certainly can identify . 22-caliber bullets,? said Jay Mason, Supervisor of the Firearms and Toolmark Unit of the Northern Virginia Forensic Laboratory. That puts this one to rest.

As the bullet is propelled through the barrel, the grooves exert a rotational force on the metal surface that's so strong it leaves marks. Under a microscope, these striae are all distinctive and different ? and they will correspond to the grooves inside the barrel of the gun that fired the bullet.

The bullet casings can't be traced back to the gun, but the bullet can be, due to the rifling imprints left on the bullet as it travels down the barrel. The serial number allows the gun to be traced to its owner (if the state requires the owner to register their gun).

Sometimes, even bullet casings have serial numbers on them, and this has been a useful tool for tracking down criminals. There are many pros and cons to requiring serial numbers on ammunition, and both sides are worth exploring. Currently, there are no strict laws in America requiring ammunition to have serial numbers.

Not likely! ? A recovered fired bullet, the spent casing too, can and will be traced to a specific firearm, if they can obtain enough to warrant that action. The rest is obvious.

Think of it like fingerprinting In the same way, a gun imprints the bullet that is being fired. These imprints may be microscopic, and they are almost always impossible to identify for someone without the proper training.
