They're made in Argentina, and they are locally available. I read one review online where a guy claimed that they have hard primer cups and cause him malfunctions, but who knows what his skill level with reloading is? Others responded that they work perfectly fine for them.
I'm looking for first-hand experience here, not 'don't buy foreign junk' responses, please. I am in serious need of primers.
They are available (in bulk) here: https://zincpoint.com/ammo-component...imers-2000-ct/
