I moved out of my parents house temporally in MA to go to school in florida. What is the best and cheapest way to ship ammo and some firearms to my new address in FL. Do I have to ship the them to an FFL or can I ship them directly to my FL address since the guns are already in my name? What about shipping ammo in the postal services new flat rate shipping boxes, you think that would fly? Do they x-ray the boxes to see what is inside them?
