In addition to acoustic-based detection, it is possible to detect the muzzle flash of a bullet being fired with an optical array. In some instances, a very sensitive array under ideal conditions may even be able to detect the presence of a passing bullet by the friction it generates as it moves through air.

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. After all, the bullet might have mushroomed or fragmented on impact.

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.

A barrel will produce individual markings in addition to a bullet's land and groove impressions as the bullet passes through, and it is these unique markings that an examiner evaluates to determine whether a given bullet was fired from a particular firearm.

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.

Bullet spread is a function of the shooter, not the weapon. Weapons on burst or full auto will show some spread because of the recoil, yes. Some spread is also common with single shots as not every round will perfectly go where the last one was unless the shooter is very practiced.

Even though the heavier bullet starts out slower it doesn't always slow down as quickly so that the flight time stays very nearly the same. As a result the bullet drop is very nearly the same. All of this tells me that sorting bullets ing to weight is a waste of time ? except for one thing.
