The Civics Project: A constitutional ban on bullets would be a difficult target

While bullets are not specifically mentioned in the Second Amendment, it is likely that the Court would find that a prohibition on bullets would prevent the exercise of the individual right that was recognized in the Amendment. If requiring trigger-locks was too far for the Court, I suspect the prohibition of bullets would be as well. While a state could make bullets more expensive through taxation, even that would probably face Constitutional challenge if the tax made the cost of purchasing bullets prohibitive.
