What type of projectile is typically found in centerfire shotshells?

In centerfire shotshells, it is typical to find slugs or pellets as the projectile. Shotshells are designed specifically for shotgun use and are filled with a variety of projectiles that can include either multiple small lead or steel pellets, often referred to as shot, or a single larger projectile known as a slug.

Pellets allow for a spread pattern when shot, making them effective for hunting birds or small game that requires a wider shot pattern. Conversely, slugs are used for larger game and offer accuracy over longer distances due to their larger mass and streamlined design. Therefore, the focus on slugs and pellets in this context aligns with the characteristics and intentions of shotshell ammunition. This understanding is key in recognizing how different projectiles are employed based on the hunting scenario and target species.
