I know absolutely nothing about slugs, but I'm trying to figure out what type to use for my Benelli Super Nova. I have a 28" smooth bore and an 18.5" rifled slug barrel. I'm curious about what slugs to use in what barrels, and what type of application they have. I'm in Illinois and we can't rifle hunt deer. Is there any advantage to using a longer smooth bore barrel over a shorter slug barrel? I also have my Super Nova set up in a more HD manner with the 18.5" barrel, but I have 00 buck shells. Is it a bad thing to fire anything other than slugs out of a slug barrel? Any help is appreciated.
