The way I read it on the BATFE site nonresident aliens cannot purchase ammo in the USA. All ammo to be used has to be listed on the form, cannot leave any behind etc.
A friend who travels to the US extensively for Three Gun and Cowboy Action shoots has also told me he has to bring all his ammo with him.
Hey, I would love to be proven wrong as I think it is BS.
No ID is required and if you pay cash no one will know you are Canadian.
