I fly with handloads fairly regularly with no problems. My handloads are in plain MTM slip top boxes with a rubber band around them, not factory boxes. As long as the cartridges are properly secured nobody cares.
I do put my MTM boxes inside a yellow Pelican 1200 case with TSA locks when I am traveling outside of the USA. This case is placed inside of my checked luggage. Of course I always find a little card inside of my checked luggage when I reach my destination telling me it has been opened and inspected. Always declare your ammo at check-in.
