I have read with smokeless powder that there is a danger of powder igniting ahead of the rear portion of the powder column. I believe this is related to a SEE event. Does black powder carry that same risk or does it all instantly burn regardless of ignition point in powder column?
As an example imagine you had a 60 grains of black powder loaded in a barrel and it occupied three inches of the barrel length measured up from breech face. If the touch hole was 2 inches from breech face would that cause a dangerous secondary type explosion effect? How far up the powder column load could a touch hole be safely located?
