While looking for brass, I found a 30-06 case for which I cannot determine the manufacturer. It is Berdan primed, is made of steel and is a somewhat shiny grayish color. I have used two magnifying glasses, to double the magnification, and I still cannot make out what the three small symbols are in the head stamp. The letters, SPRG and numbers .30-06 are also on the head. The interesting thing about the case is, about 3/8" from the extraction groove, there is an indented ring around the case. The ring is about 1/16" wide and about the same depth. Any ideas?
