Some years ago I found an interesting 7.62x39mm cartridge in a box of mixed range pick-ups that came out of Israel. The case was a typical Soviet copper washed steel with thae headstamp “17 58”, but the projectile had an unusual profile and was cupro-nickel jacketed. Not knowing what it was, I carefully pulled the projectile. This was easy as the case was corroded somewhat at the neck and some of the tension was gone. Turns out that the projectile was a .303 British Mk VII! Under the projectile was a piece of yellow foam padding which was covering a small powder charge of what appeared to be the normal type used in this caliber. It took a while for the puzzle pieces to make sense, but I concluded that this was a “homemade” subsonic load. Years later, Russ Cornell told me that this cartridge was most likely made in Rhodesia, as were several other variations that used the regular PS ball projectile with a reduced powder charge. Does anyone have any information on these “homemade” subsonic loads or can confirm that this was done in Rhodesia or maybe South Africa? Supposedly, better condition specimens have a red tip?
