Exactly.

If they ask whats in it, just tell them Antiques.

The real problem is that most employee's have no clue what a muzzle loader is. You say firearm and they throw up their hands and say they cant do it. Its just a lot easier to say its either antiques or something else.

Last time i shipped fedex the lady asked me what it was. Told her it was 2 gun stocks. She asked about a barrel and i said nope, just 2 stocks in there.
