The first price list I have for Remington Arms showing Load Index numbers is 1936. I have the Retail catalogs for all years from 1927 forward. The Retail catalogs do not show the numbers in the 1930’s. Only the Price Lists for the 1930’s have the numbers. What is the earliest box or Price List do you have with a Load Number. I have seen a box from about 1925 with the number R331 for .45 Colt Black Powder Loads. I’m trying to establish when they first assigned Load Numbers to the Metallic cartridges.
U.M.C. had started to use Load Numbers for Factory Loaded shot shells at least by 1901. I have the 1890 U.M.C. catalog and no numbers are used. My next catalog is 1901 and they are in use at that time. Could anyone with any catalogs between 1890 and 1901 please check for an earler date. I would guess it would be about 1895.
