DaMadman,
Are you SURE about that? I ask only because California's law is very similar to Maryland's law and I know for a fact that here in California, if you leave the state with a "hi-cap" magazine it is a felony to return with it...regardless of ownership status. The intent of the law was to ultimately and eventually "make extinct" any hi-cap magazines...period!
It sounds like a great loophole to be able to go out of state and personally bring in a hi-cap but I can't imagine any modern day anti-gun, liberal legislator letting that one get by!
Just food for thought.
btw, gregarat....from the title of your post, I thought that you were trying to figure out how to import that extensive Playboy and Hustler Magazine collection of yours to Florida!
