the ammo is called winclean. the powder is proprietary. You can't buy it.
Also the primers are part of the reason the cases are clean. And no you can't buy them either.
I have a load that come very close to that clean,
CCI lead free primers, clays powder and a 124gr CMJ bullet in a 9mm case.
Still amazes me that with the current health awareness, that the Surgeon General or someone hasn't forced Winchester, Federal, etc to release lead free primers to reloaders..
