I have a BELL .50 caliber basic case with the headstamp “BELL” at 12 o’clock and nothing else. This is a rimless case with a standard extractor groove. The case is 3 inches long. The head just in front of the extractor is 0.542 inches and the head itself is 0.534.
What case types was this basic case meant to be formed into? What was Bells name for this basic case?
