Kuduae,

I'm sure you're right. It's my brother who has the PhD in Chemistry. However, I am equally sure that I'm right about the burning temperature of cordite and its extreme destructive effect on barrel steel compared to modern powders, irrespective of their composition.




You are both right, its a Double Base powder and "hot" burning as its a degressive non coated powder (high initall pressure).
All SD and DB powders today are coated to alter burn carestics. The base is usually the same and together with its shape they make the different burning rates.
