I'm not new to reloading Berdan-primed cases. Previously, I've successfully reloaded the following Berdan primed cases:
1. 7.92x57:
German 1935 Polte
Czech 1950's clandestine (no headstamp)
Turkish 1950
Ecuadorian 1955
Yugoslav 1954 (Igman) and 1955 (Prvi Partizan)
Romanian 1973 and 2014 steel case
2. 30-06:
Iranian dated 44 (1344=1964-1965)
Belgian FN 57 and 58 (1957 and 1958)
3. 7x57:
Spanish FNT and PS from the early 1950's
Belgian FN 36 (1936)
4. plus Swiss 7.5x55 GP11 from the late 1970's and early 1980's.
But I'm having trouble with Iranian 7.92x57 dated 35 (1335=1956-1957), and I've got 1,000 of 'em. I found that out of 100 Iranian 7.92x57 factory loaded cartridges NONE of the primers would go off. The firing-pin-indented Berdan primers, however, come out easily with an RCBS Berdan depriming hand tool. When reprimed with Tula-brand 2011-vintage Berdan primers they still wouldn't go off. The anvils in FN primer pockets are 53 thousandths below the base; the anvils in Iranian 30-06 and 7.92x57, Ecuadorian, Romanian, and German primer pockets are 60 thousandths below, and the anvils in Spanish primer pockets are 65 thousandths below. When reprimed with the Tula primers seated from 4 thousandths (Belgian FN 36, 57 and 58) to 11 thousandths (Spanish FNT 1952) below the base, all BUT those seated in Iranian 7.92x57 cases go off. Has anybody encountered or, even better, overcome a similar problem?
