WRA 7.92 x 57


#1

Does anyone know when and for whom Winchester produced a 7.9 x 57 headstamped WRA 792? It is obviously a military load, with pointed copper full metal jacketed bullet and a ring crimped primer with red annulus. Was this possibly for England?

Looking through some of the responses to another 7.92 x 57 discussion today, I see John Moss touched on this headstamp, indicating it was probably made during WW2.
