The Production of .30/06 Blanks (crimped Star, six folds) did NOT cease in the 1980s, but at least after 1992…Australia bought several Tens of Millions of Rounds of AMA 90, 91, 92 and 93 .30/06 Crimped Blanks in the 1990s; They are “not reloadable” ( ie, Berdan .217/5,5mm ); we in the Movie industry use them to form 7,9 blanks and 7,7 Japanese Blanks, by Hydraulically decapping., trimmed of the crimp section, and reformed.etc.).
Also, the US Army Ammunition procurement agency, in the late 1990s put out a tender for .30/06 blanks for use by VFW Funerals etc, to replace the terminated Lake City .30 cal production. They finally settled on AMA, at least for the first delivery…later, they also got CBC to produce some as well. Both were “repacked” in the USA before distribution to VFW Posts.
Finally, in 2005, Lake City did another run of .30 cal Blanks, this time crimped, but using the 7,62 M82 Blank Form Drawing, and sizing it to .30/06. as all the .30 cal drawing tooling had been disposed of by the 1990s, or converted to 7,62 Calibre. Cases can be distinguished by Date, and the extractor Groove which is 7,62 Nato Wide style, not the older, narrow .30/06 style.
