True or False: Rifling is found inside the bore and consists of spiral lands and grooves.

The statement is true because rifling refers to the helical pattern of grooves and lands that are cut into the interior surface of a firearm's barrel, specifically in rifles and some handguns. This design is essential for stabilizing the bullet as it travels down the barrel and exits, leading to improved accuracy. The spiral lands and grooves impart spin to the bullet, which helps maintain its trajectory, reducing the effects of drift and improving overall precision in shooting.

Rifling is not found in smoothbore firearms, such as most shotguns, where the interior does not have these defined grooves. Therefore, the correct response captures the fundamental role of rifling in enhancing the performance of rifles and certain types of handguns, distinguishing them from shotguns, which rely on different principles for propelling shot.
