When LC ceased production of .30 cal Ball in the late 1970s, early 1980s, they were still using up large quantities of M1909 Blank made and packed by LC in the 1960s from cases stretching back to the 1930s dates ( all factories and HS Dates, including “Match” cases).
In the late 1980s, early 1990s, the relevant Army department put out a procurement for “M1909 compatible” .30/06 blanks world wide, specifically for VFW Funeral use, and this was initially supplied by AMA of Denmark, which in 1990 was still making .30 Blanks (with Star crimp Mouth) for use in Garand M1s, BARs and M1919A4 Guns in Danish service, and for Foreign sales ( Australia bought about 50 mil. rounds of the Blanks then). The AMA blanks were repacked in the USA to meet US DOT requirements…why I don’t know, as AMA already packed the blanks in M19 Steel ammo cans, as per normal Milspec.
Then the late 1990s, early 2000s, CBC (Magtech) Brazil was also approached for a supply of Blanks, but as to how many were acquired, I can’t say. They too, were Star crimped Brass blanks.
Then Lake City came back with the 2004 contract, but used case draws from the 7,62 M82 Blank production line, but with different Body and Neck forming steps, …and the neck star crimp. ( The 7,62mm M82 had already abandoned the paper wad seal back in the mid 1990s, for a star crimp ( short size). BY 2000, all the .30 cal Plate-loading machinery had either been disposed of, scrapped, or was otherwise unusable.
Except for this special VFW Blank, no other .30 cal production has been undertaken at LC, nor is ever likely to be.
