Some time ago I downloaded an incredibly good book : "Ammunition Making"by Frost ,which was published already many years ago by the National Rifle Association. Here I found all the info I had always been looking for, about cartridge manufacturing, especially info about primer manufacture. Mr. Frost writes, that in 1988 the british company ELEY came on the market with a new primimg system technology in which the components could be dry loaded because no primary was used, instead to this so called dry "Premix" a drop of water was added, which made the components react and form the friction-sensitive priming composition after drying. This is a technology especially applicable to rimfire ammunition. Eley was trying to sell this new technology to potential other cartridge manufacturers. I had a look at the patent literature, but did not find any Eley patent for this technolgy. The only patents I found, all after 1990, were for the use of KDNBF and DDNP as primaries together with boron or glass. The socalled "Eley Premix" is supposed to not contain any primary. Does anybody here know anything about this now more than 30 years old technology ? I would like to understand the system used. Which components make up the Premix and what is the result of the reaction after adding water ?
