Can police track bullets?

Do bullets have serial numbers?
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.
Can you trace bullets?
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.
Are hollow tips traceable?
No. The only way a projectile can be traced back to a particular firearm is if a recovered projectile is in a mostly intact condition. It can be slightly deformed at the tip, but the base and shank must be intact for microscopic comparison.
Do criminals use hollow points?
