It’s true. Tom talked about it on today’s show. Pertains to a pistol which fires it, so it’s classed as “cop killer” ammo, and banned.
It still seems to be available, $250 for a 1080 count can.
I bought it cheap and stacked it deep.
The last russkie stuff I bought was $125 a can, it was $65 before that but it is still around at $260 and climbing.
