The Germans during WWII had an interesting approach to this. Rather than a
single charge the Hochdruckpumpe section gun had firing chambers paired side
all along the barrel. Each of these had charges that fired in sequence. The
ejection rate was reported to be 4500 ft/second. I think the explosive was
coal dust! Talk about a cheap shot!
One 150 yards (meters?) long built in Calais was reported to be able to fire
150mm shells to London!
Ah, such usless information I remember. Now if I can just rememver the
shoping list.
