How far can a shotgun rifled slug penetrate effectively?

A shotgun rifled slug is designed to provide greater accuracy and improved range compared to traditional shotgun pellets. It achieves this through its design, which allows for it to spin in flight, much like a bullet, leading to a more stable trajectory.

Typically, a shotgun rifled slug can effectively deliver lethal energy and maintain a sufficient level of accuracy out to about 100 yards, making this range appropriate for various hunting and tactical scenarios. At this distance, the slug retains enough velocity and terminal performance to be effective against larger game or for defensive purposes. While penetration and energy transfer can vary depending on factors such as the specific load, barrel length, and target material, 100 yards is commonly recognized as the maximum effective range for rifled slugs in firearms training contexts.

Beyond this distance, the performance of the slug may diminish significantly, making it less reliable for precision shooting or effective penetration.
