Worth pinning down, because “ammo” is doing a lot of work in this question.
Federal: 18 U.S.C. § 922(g)(1) bars a person convicted of a crime punishable by more than a year from possessing any firearm or ammunition. And § 921(a)(17)(A) defines ammunition broadly: “ammunition or cartridge cases, primers, bullets, or propellent powder designed for use in any firearm.” So it is not just loaded rounds. A box of spent cases, primers, or loose bullets can be “ammunition” too.
Possession also is not limited to holding it. Constructive possession (ammo in your car, closet, or a bag you can reach) supports the same charge, and that is where a lot of these cases actually come from.
The real gray area is the black-powder point above. The Act excludes “antique firearms” from the definition of firearm (§ 921(a)(16): made in or before 1898, or a qualifying replica), which is why muzzleloaders and their powder sit in a gap. Fixed cartridges for a modern gun do not get that carve-out.
And “illegal everywhere” is the default, not absolute. If the person’s firearms rights were restored (a state restoration or a qualifying pardon), they can fall outside the prohibited class (§ 921(a)(20)). That is state-specific.
Not legal advice. The only real answer for a specific person is a lawyer in their state.
Genuinely curious: has anyone seen a prosecution actually turn on the antique-firearm carve-out, or does it basically never get charged either way?
