today i found a lot of useful technical info on primers. But as i was reading three different books i do not remember which one had the real good set of fornulae.
2 books were free as they were over 95 years old.
when i get back tot he office i will look them up and post the info.
by the way one of them was detailing how to make non corrosive primers as used by the germans since 1907 and the swiss since 1911.
what i mean is that they actually show the chemistry and practical way to make mercury fulminate from nitric acid and mercury, how to make it non corrosive and stable. without using chlorates.
fascinating really. ( BTW i am a chemical engineer by training and profession)
