This specific ammunition refers to a shotshell firing a single, large projectile, typically made of lead or other dense materials, designed for smoothbore firearms. The measurement signifies the shell length, a less common size compared to the more prevalent 2 -inch and 3-inch variants. These projectiles are chosen for hunting large game or when increased stopping power is necessary.
Historically, such ammunition was developed for improved terminal ballistics compared to traditional shotshells loaded with multiple smaller projectiles. Longer shells can accommodate heavier projectiles, resulting in greater energy transfer upon impact and improved accuracy at longer ranges. This enhanced effectiveness made them a popular option for various applications beyond hunting, including law enforcement and self-defense. The choice of specific shell length often balances firearm compatibility, desired projectile weight, and recoil management.
