What Makes a Bullet Accurate
- Firearms and bullets have come a
long way in the last hundred years.
- There were two main improvements
to the bullet that made it significantly more
accurate and reliable:
- The first was the shape of the
bullet, taking on a more oblong cylinder shape
with a rounded tip. Making it more aerodynamic
then the former sphere shaped bullets.

- The second improvement was
rifling of the barrel, where spiraling grooves
were cut into the inside of the barrel to
allow the bullet to spin as it left the
barrel. This spinning motion of the bullet
creates angular momentum force which causes
the flight of the bullet to be much more
accurate and less easily affected by outside
forces. This process is similar to spinning a
spinning top versus a
stationary object, if you nudge a top it will
continue to spin, if you nudge a stationary
object it will just fall over.
