Is dynamite a pure explosive?
Well for starters, traditional dynamite is about 45% (ish) Nitroglycerine and the rest of it is not a pure explosive (a common misconception is that dynamite is TNT - NOT true), whereas C4 is about 90% pure explosive so if you had 1 stick of dynamite of 500g, and a stick of C4 at 500g I suspect the C4 would do more damage but you'd have to compare the pressure of detonation for NG and RDX and then you'll get a better answer - sorry that's not exactly comprehensive but it might be of some use!
