I am rarely asked what's in the package. I just put the appropriate amount of insurance on it and send it. When I have been asked, I've responded "it's a rifle" and no one seems to care. I started a claim once on a rifle that was lost in the mail (sent from me to my gunsmith/FFL). My local postmaster that was helping me with it said I'd done everything right, I had insurance, I had tracking, and I was sending it to an FFL... no issues. The rifle ended up showing up at the FFL and I never pursed the claim. Not sure if any of that helps...
