Avoid "Large Capacity Ammunition Feeding Devices", which amount to any magazine, clip, or belt that holds more than 10 rounds.
Don't import AP handgun ammo.
Tracers and incendiaries are illegal (except for shotguns, which have an exemption thanks to flare guns).
Otherwise, you're fine here for any number of complete cartridges, any type I didn't list, and any caliber (provided it's not a grenade or destructive device).
(Don't bring a loaded gun with you either. Keep the guns in a locked case with no ammo in the firearm. Ammo may be in the same locked case and even in a magazine, but not in a mag that's in the magwell or in the chamber.)
