What is the point of a rifle barrel for a shotgun is it only to shoot slugs and do you need it to shoot buckshot or will your normal barrel work with buckshot:confused::confused:

The point of a rifled shotgun barrel is to impart a spin on a slug for the purpose of ballistic stability - exactly the same reason as the rifling in a "rifle" barrel. Objects (in this case slugs and bullets) tend to remain stable and resist tumbling, rolling, and yawing through the air, if they're spinning around their longitudinal axis.

Buckshot, on the other hand, is not "an" object, but rather many objects contained within a plastic shot cup inside the shotgun shell. When this shot cup travels down a rifled barrel, a spin is imparted on the entire shot cup and it's contents. When the shot cup exits the end of the barrel, the spinning cup scatters the buckshot over a much wider area than would otherwise be in a normal pattern from the same choke. This wider pattern tends to be so large (depending on the distance from the end of the barrel) that the pattern has large gaps in it to the point of being useless for hunting.
