I came across this case of 7.62x39 tracer ammo. I know a decent amount of this stuff has been showing up lately, but the question is how did it make it into the country? I thought tracers could not be imported. While these were made in 1978, they were last inventoried in 2001 (according to the tag on the front of the crate). So they had to be imported sometime after 2001. I know stuff sneaks in, but it seems that someone would have noticed several pallets of tracer ammo. Any thoughts?
