I'm trying to track down information on some old surplus 7.62 CBC? It was suppose to be recalled because it was dangerous. I remember reading about it in one of the forums, but can't find the info now that I need it.
 
"Surplus" Cartridges Dangerous
Companhia Brasileria de Cartuchos, CBC, says its 7.62mm x 51mm cartridges from lots dated 1975 pose serious safety risks because of excessive pressures. The cartridges, headstamped "CBC 7.62 75", should not be used, given away or sold under any circumstances. There have been reports of rifles bursting as a result of the excessive pressure. An independent testing lab detected peak pressures in excess of 130,000 CUP, in one of 20 of the cartridges it tested. CBC calls these rounds outdated.

The particular round was manufactured solely for military use in several countries. They are not intended for civilian use at all.

CBC also has issued a warning for any of its 7.62mm x 51mm cartridges from any year which have a label on the packing material with the Spanish word "reengastada." The label was not affixed by the manufacturer and its application to ammunition is unclear.

If you have any ammunition with the 1975 headstamp or with the Spanish word, contact CBC at 800-742-1094.

– Originally published by the author, un-bylined, in the 1 June 1992 Firearms Business.
That toll-free number is no longer operative (2007) but it was answered in the San Francisco, California offices of Brobeck, Phelger & Harrison where CBC was being represented in this matter.

Deconstructed CBC 76 7.62mm round, courtesy of www.chinesefirearms.com According to the attorney, Gary Fergus, on point at the time they were contacted in Spring 1992, the suspect "CBC 7.62 75" cartridges had been involved in 83 catastrophic failures of small arms ranging from numerous M1A/M14 rifles to machine guns such as Kent Lomont's M1919A4 and M2 "Ma Deuce," both of which were destroyed at the April 1992 Knob Creek meeting. He had obtained the rounds from Century International Arms.

In an interview by fax from Sao Paulo with CBC's President, Antonio Marcos Moraes Barros, it was learned that his company had originally manufactured those particular rounds on an Argentinean military contract. He was unable to provide any information about how the ammunition came to be made available to Century, which had imported the bulk of it, or Samco Global Arms, only that neither of those concerns had obtained it from CBC.
