my wife recently got a shotgun for hunting. It has a rifled barrel and I know that if I shoot shot through it that it will really mess up the shot pattern but I am wondering if it will mess up the barrel. I want to use it for home defense and the farthest distance of open space in my home is about 25 feet so I am not too worried about the pattern but dont want to damage the rifling. Anybody know if shooting shot through a rifled barrel will ruin the rifling.
