getting back to the original question.
According to the firing tables (though admittidly not the most upto date version) the max vertex of a shell for the 105mm L118 gun is approx 7500m, which is actually fired at a lower chanrge than top charge due to the limitations on the QE of the gun. If you ignored the limitations and dug a damn big hole for the breech then you could probably get higher, but also probably end up with a buggered gun.
do i sound too much like a spotter now? I'll go away now.
