If that was either of those very highly (heat, shock and static) sensitive compounds in the amount of stuff we are seeing in there, there would possibly have been a detonation already, in the ammo maker's machinery.

If that amount of stuff is either of those compounds is would surely cause an over pressure situation, as normal primer pressures can reach 25K psi.

Chemical letter for uur is S...
Nitric acid is Formula: HNO3  Hydrogen, Nitrogen, Oxygen (no sulfur)
Trinitrotoluene or TNT is resonant ring structures toluene Formula: C7H5N3O6 (no sulfur)

Here is what is found in Blue Dot's Chemical formulation
Nitroglycerin is also known as tri nitroglycerine or 1,2,3-Trinitroxypropane, triple Nitro groups using glycerol Formula:

Hey Shadow:
I hate to keep beating this but read the process for manufacturing Nitroglycerin:

Manufacturing

The industrial manufacturing process often uses a nearly 1:1 mixture of concentrated sulfuric acid and concentrated nitric acid. This can be produced by mixing white fuming nitric acid—a quite expensive pure nitric acid in which the oxides of nitrogen have been removed, as opposed to red fuming nitric acid, which contains nitrogen oxides—and concentrated sulfuric acid. More often, this mixture is attained by the cheaper method of mixing fuming sulfuric acid, also known as oleum—sulfuric acid containing excess sulfur trioxide—and azeotropic nitric acid (consisting of about 70 percent nitric acid, with the rest being water).

The sulfuric acid produces protonated nitric acid species, which are attacked by glycerin's nucleophilic oxygen atoms. The nitro group is thus added as an ester C-O-NO2 and water is produced. This is different from an aromatic nitration reaction in which nitronium ions are the active species in an electrophilic attack on the molecule's ring system.

Seems like there's a little Sulfuric there somewhere

As I said, I'm not a Chemist, but I've hauled tens of thousands of tons of Nitrates over the years and I know for a fact that Sulfuric is used in the process of making a lot of different Nitrates
It may not be noted in the final chemical make-up, but it is still there
As some Elements breakdown or decays, it become another

You really need to talk with a Chemist and not just dismiss a theory
