Last week, I lucked into 5 boxes of Remington factory .30 Remington as part of another deal. These boxes were of the more recent design, with the front (or top) half green and the rear (or bottom) half yellow. By using the decoding method described in IAAJ #469, these appear to date between 1985 and 1991. Would that date range be correct for this box design? Or am I off by 11 years?
Codes were D23U (1985?), K21C (1988?), R18K (1991?), and two which were E22C (1986?)
Second question - When did Federal start loading centerfire metallic cartridges commercially? I think maybe sometime in the 1960s, but I am not sure. I have four boxes of Federal cartridges in the “flip top” box configuration in .38 Special and .45 ACP, the one where one box end is hinged, sort of like a Marlboro cigarette pack. About when were those on the market?
