Is Fabrica Palencia 5.56mm ammo any good. I know it is Spanish mfg. The Headstamp on the case was 80 and 12. I have seen reports that it is a 62gr bullet. One report I read, says the AR-15 extractor pulls the rim off the case. One of my recently divorced friends was thinking about selling his small stock of it. Is it any good...??? Worth risking your life using it...???
