Primer manufacturing- Why not ?

[John Kepler]

Not to mention that the manufacture of the primer mixture itself is a rather complicated (if you want commerical grade material) and potententially dangerous process.

Potentially??? Bud, if it's "shock-sensitive" enough to be used as a primer, there's no "potential" about it....it's dangerous stuff! Not to mention the "L" word (lead as in lead styphnate) making it highly toxic to work with as well.
