This was basically a short round- nosed bullet with a deep cup in the base. The cast rifling has little or no effect in spinning the projectile as it passes through the air.Īnother early design was the Foster slug. The wad provides drag stabilization by moving the centre of mass forwards. The original Brenneke slug overcame these problems via the use of a solid lead, pre- rifled projectile with an attached plastic, felt or cellulose fibre wad. Being elongated, it is also preferable for the missile to be spin stabilized to prevent it from tumbling. To enhance a slug's performance, both externally and terminally, it requires to be elongated and to have its centre of mass moved forwards. However, a smooth-bored shotgun firing a round ball is essentially a musket with its inherent short range and accuracy problems. Since it is a symmetrical projectile, it will not significantly deviate from its intended path if it begins to spin due to air pressure. The simplest form of slug is a round ball (sometimes referred to in the United States as a pumpkin ball or pumpkin shot). Shotgun slug ammunition is available in most of the common shotgun calibres. A shotgun slug is a single projectile primarily designed to be fired from a smooth-bored shotgun.
