I have the original.





Please note the bold print at the top of the graph. Too many times in the past incorrect assumptions were reached regarding these tests. They developed these loads to all have the same muzzle energy. They state that the Dupont Oval load is special. In the bottom image, they included a 5th load, progress nitro. It produced a lower peak than black powder.

10" out from the breech and they are all above 3000. It seems to me that is pretty close to my hand....
