Everybody has a Powder Burn Rate Chart showing fastest to slowest powders. I've got several.
However this only tells part of the story. All Explosive Combustion Speeds are rated in Feet Per Second. IE: C4 is around 32,000 fps. The faster it burns the bigger the pop and the more powerful/effective it is..
Gun powder is rated the same way except we never see those numbers.
Point being, there could be a big jump in speed between two powders that are right next to each other, and then a small jump to the next powder. Powders like H110 and W296 and several others are exactly the same but don't occupy the same line in the chart. One is above the other and I have even seen several others in between.
By knowing these numbers we could pick powders more accurately, and obtain better results.
Does anyone here have a Burn Rate Chart that gives the FPS of each powder's speed of burn?
