      My camera goes up to 1/4000 s by Tomo2005-05-05 09:34:55
        So using that speed and some quick guesses... by AndyA2005-05-05 09:44:06

              or e) slower velocity by tallastro2005-05-05 10:13:04

                  What I know of charges by Yaeger 2005-05-05 10:46:21
dates back to 92/93.

(This is for a 155 mm gun).
Max 8 charges of powder, one black, the others gray. All charges are one kilo in size. (Not sure about that).

For targets nearby, only the black powder is used. As the range increases, gray powder charges are added. The gray powder charges have different burning speeds (it isn't really powder, it is in a pellet form, with a number of holes in each pellet to influence the burning speed).

But as I said, it was a long time ago. Oh, and a great shot :)
