I could be mistaken but as I understand it, the ban on Russian ammo is actually a ban on a bunch of stuff that includes Russian ammo.
The ammo portion of the ban (and maybe all of it) is being done through the licenses to import Russian products not being issued. However the currently issued licenses will still be valid, but will not be renewed when they expire.
Licenses are usually for three years, so some licenses will still be valid for years. However, it’s not just the time until expiration, when the license was applied for, they have to include how much they will import. So some licenses might end before they expire b/c the license holder has reached the limit of what they were approved to import.
The ban is only for one year, but we don’t know if it’ll be renewed every year.
There’s also a chance that someone will open up a business in a neighboring country such as the Ukraine, and start exporting the ammo from there.
So it still sucks, but it’s not as bad as it could’ve been
