In shotgun shooting, the grouping is also called the pattern or "spread". The pattern indicates the extent of scattering by shots from a single shotshell, measured as the smallest circle containing all the shots on the target.

For instance, an offset choke can be used to make a double barrelled shotgun with poorly aligned barrels hit the same spot with both barrels.
