The 350 Legend exists to satisfy a political idea. It really doesn't offer anything that wasn't already available other than to comply with some nonsensical rule. It's a piece of hunting equipment that has been mandated by people who don't hunt and don't know anything about guns. If the rule didn't exist, neither would the cartridge. If some jurisdiction restricts handgun bore diameter, then maybe the 30SC will make some sense. Otherwise, I think it dies on the vine, an answer to a question that no one asked.
