The original experimental spotter round for the SMAW was a 7.62x51mm, but with a long unjacketed lead bullet holding the tracer and flash element. It was found a larger bullet was needed so they moved to the 9x51mm.
I need an example of the 7.62mm version (which also used the .22 Hornet blank high/low pressure system) if anyone has one.
I also need the 9mm version with the yellow and red tip and also the chromed case type. The latter is used as the top round of the magazine so that corrosion/electrolysis does not take place in storage.
