Irrational Hatred
People who say "less" when they mean "fewer" ought to be turned into soup, the soup fed to baboons and the baboons fired into an active volcano. What has you grinding your teeth with rage, and why?

Bullets do not go in straight lines!
Where to start...
In deep space, far from planets, in a vacuum, bullets will go in (approximately) straight lines.
On a non-rotating airless planet, they go in simple curves, pulled down from the straight line by gravity.
On a rotating airless planet, they go in rather more complex curves, with the exact path differing if you're shooting north, or west, for example, as well as with how far north you are.
On the real earth, variations in air pressure change the overall shape of the trajectory, as does humidity and temperature. Wind blows the bullet off course.
There are also experimental manoeuvring bullets, these vary from new and exciting tech, to stuff that was used in WWII(?) where you shoot an artillery shell on a curved path, and then a rocket motor lights up in the front of the shell, and shoots it back towards the gun, where it's recovered, and the pictures the camera has taken are inspected.
