Still no primers!

Bullets are not explosive, do not have as much danger in forming the compound, and bullet casters have many years background forming the alloys with being careful not to introduce water into the melting plot.

I have the NRA book on manufacture of primers, experience with rocket fuel handling in the Standard Missile and Stinger Missile and this only serves me to question the knowledge base and experience of those advocating primer manufacture. These are explosive devices that require knowledge and safety practices. 

Granted, the Israelis did make primers out of matches for recovered .303 British with Berdan primers. They had two advantages: 1) they did not need to make an anvil, and 2) they could flatten the recovered primer cup for reuse. Also, they made powder from used film negatives for the nitrocellulose. These only had to function well enough to stop a soldier with new ammunition they could recover. These were not long-range accuracy rounds.

A problem in the manufacture is the usage of microscopically fine ground glass or sand mixed in the powder to function as super-hot ejecta going into the powder mass to aid uniformity of ignition. Where to get either the glass, or sand, and how to mix is another question. 

Another problem is procuring the ingredients and then how to mix. Mixing the compound can be either dry or liquid. Each time is another possibility, we cannot rely in statistics to produce a safe environment. No one looks good with missing fingers or powder burns across their forehead.

Also, primers can affect pressure and how do you test the explosive force and the range of pressure using this explosive force?

With proper manufacturing equipment and safety equipment spread over the time of manufacture you will approach the current cost of primers. 

Not to say this cannot be done, but there is a heightened cost and safety factor. 

Personally, I'll go to shooting flintlocks before making my own primers.
