The answer to the nearly weekly quest for Aquila ammo.
The whole Aquila ammo thing should be a sticky, IMO. It does not help that the search engine here is near useless.
Read the Importing Ammo info in the ammunition forum. Go to the NRC link provided, and look at the list of approved ammo. Search for Aquila.
That'll get the most up to date list of ammo approved for import. If it is not on the list, you won't find a reliable source for it, and the stuff you see otherwise, has quite probably been brought across the border by someone unaware of what laws they were breaking, Exporting ammo from the US. Or they knew, and risked it anyways.
There was supposed to be a fella in Montreal that was getting approval for the Aquila line of ammo, to distribute it. Strange situation. The ammo is made in Mexico, the distributor for North America is in the States, and selling all he can get there, so apparently sees no real need to pay the fees required to get an export licence.
Add all that info, some of which I am reasonably certain that has basis in fact

to that the Aquila stuff I have had in the past was all low grade crap of the cheapest sort... Buy the stuff you can get and don't worry about it too much.
