Finely ground black & smokeless powder burns faster
Very light loads of
fast burning smokeless powders in large capacity cases MAY create very high pressure.
Secondary Explosive Effect may occur with very light loads of
slow burning smokeless powders in large capacity cases.
Detonation of smokeless powder has NOT been demonstrated in a shotgun shell.
Interesting reading, but one could read opinions for weeks, and the ballistic science is way beyond me
