you would need to contact the dept of law enforcement in each state you go through and let them know. they will inform you what to do in each state but get names of who you speak to in case one makes a mistake. if you fly, all you need to do is declare the firearm to TSA and you do need an FID or LTC in MA to have it when you land. they can detain you if you don't. i was a Deputy Sheriff in MA. had to take a course on it.
Talk to Mark the owner of shooting supply he is a police officer and knows the laws
