Bullet

A bullet was a projectile propelled by a firearm. Most bullets were made from a type of metal.

In the alternate reality created by Nero's temporal incursion, described the notion of transwarp beaming as being like "trying to hit a bullet with a smaller bullet, whilst wearing a blindfold, riding a horse."

By the late 24th century, weapons that fired bullets were relatively rare. In 2375, when three Starfleet officers on board Deep Space 9 were killed with tritanium bullets, Chief Miles O'Brien pointed out that one didn't see bullets every day. .

Captain Jean-Luc Picard also used bullets to kill two Borg on the holodeck by using a holographic Tommy gun.
