If you know; you know. I actually bought mine from the other seller on here and did shoot and test a few. They will penetrate a heavy tractor-trailer brake drum I found on the range, about 3/4" thick cast iron.

Don't know about tracers it was daylight too bright to see.

I have 50 rds. of the 5.56 version, $5 ea=  $250

I have three belts (185) of the 7.62 version, $7.50 ea= $1387.50

Total for is $1637.50; selling the lot for $1500.00 Will also include the fired cases so you can check condition.

Thanks!
