Nope. I fully expect a federal law taxing every single bullet sold. Buy a 50 round box and get hit with a $250 tax. Wait. It will come.
Can you imagine a $5,000 per bullet tax? Think about that. The police show up at a crime scene where someone has been shot multiple times. A cop looks at the bullet-ridden body and says, "Damn, someone must have really wanted that guy dead. They put $65,000 worth of bullets in him."
