Particles from black powder ammunition

Discharge residue particles from black powder ammunition were then examined. Table 20.9 gives representative results. 

Table 20.9 Discharge Particles from Black Powder Ammunition...

In previous casework in which the majority of the FDR particles contained potassium and sulfur, frequently at high levels, it was thought that the ammunition responsible probably contained black powder. In most of the cases the type of ammunition was not known, whereas in others the sampling and analysis of the residue from the interior of the spent cartridge cases confirmed the presence of black powder. 

This posed the question do potassium and sulfur always occur, often at high level in discharge residue particles from ammunition loaded with black powder In other words, from the presence and levels of potassium and sulfur can it be accurately predicted when black powder is used ...
