Question: 1 / 400

How are rifled barrels different from smooth-bore barrels?

They are smoother and easier to clean

They have grooves that impart spin to the bullet

Rifled barrels are designed with grooves that run along the length of the barrel. These grooves serve a crucial purpose: they spiral the bullet as it travels through the barrel when fired. This spinning motion stabilizes the bullet in flight, improving accuracy and precision. The spin reduces the impact of external factors like wind and gravity, allowing for more consistent bullet trajectories and better overall performance, especially at longer ranges. The design of a rifled barrel creates a better aerodynamic profile for the bullet, which can significantly enhance accuracy compared to smooth-bore barrels, which lack this rifling and therefore do not impart any spin to the projectile.

In contrast, the other options do not accurately describe key differences between rifled and smooth-bore barrels, reflecting aspects that do not affect their fundamental characteristics or functions.
