National Match 30-06 & 30M1 cartridges for the Springfield 1903

[Calif-Steve]

The US Army loaded up a lot of 7.62mm "Duplex" for use in Viet Nam. Two bullets loaded into the 7.62mm case. Both were light weight bullets and the idea was to use them in Mini-guns out of helicopters. They ran Ok and were an interesting idea that deserved trial in RVN. After they were made they became involved in a legal issue about multiple projectiles and a violation of Rules of War. The Army destroyed the lot and that was that.
