I have a mossberg 500 with a rifled barrel. I want to shot Game & Field Loads NOT slugs. I have some people say it will just mess up the inside of the barrel so I will not beable to ever shot slugs and some say I will mess up the barrel and gun for eveything and anything. I dont care to every shot slugs I just want to shot targets and clay. So has anyone shot game and field loads in a slug barrel. Thanks
