762×39 Ammunition

I have some extra  Several Hundred 762X39 Ammo.  I ordered this from a friend in the Military wile he was stationed in Germany. It is surplus Russian and East German machine gun ammunition. Unfortunately Customs opened the Nitrogen filled tubes and removed 200 rounds for what they said was ballistic testing. We received a letter from them a few weeks later saying that these were FMJ Armor piercing rounds and also found two Tracers rounds. 
I have found No Tracers in the several hundred that I and my buddies have fired. We have a friend that owns a Wrecking Yard and donated a Chevy truck and a Honda Accord to shoot at.  These rounds went into the front of the Honda and exited the back. Clear through this vehicle. They also went through the frame of the Chevy truck and exploded the engine block. 
NOTE ! One buddy has a Chinese Mac 90 and broke the Firing pin twice with this ammunition. We had no issues with any of our SKS AND OUR Russian Rifles. I also had some bank bulletproof glass from a job I did and it does go through it but just falls down after penetration. 
I want $70.00 per 100. Or $35.00 per 50..  Text me 479 324 0298 if interested THANK YOU
