I sent a muzzleloader one time and made the mistake of telling them and the post master wouldn't let me send it because it shoots "bullets" so I told him I'd give him 500 dollars on the spot if he could figure out how to shoot it ! Now I don't tell them it's just a box of machine parts. BTW it's legal to send a muzzleloader thru the usps but the liberals working there can override that if they choose to.
