I have just added two more cartidges to my 9.3x62 collection and would like to know a little more about them if anyone can please throw some more light on the following questions.
The first has the headstamp M+FA CSX 9.3/62 and I understand that it would have been manufactured at the government factory, Altdorf, Switzerland. In some headstamp notes given to me in the past, that headstamp has 1956 against it. Does that mean that was the first year of manufacture?
The second has the headstamp SBP Ô 9.3x62 Ô. Is this an earlier headstamp for Sellier & Bellot, Prague, Czechoslovakia? Their headstamp more recently being S & B Ô 9.3x62 Ô and then S & B Ô 9.3x62 . If SBP Ô 9.3x62 Ô is the older of them all, as of what year was it used?
