Shell and case. AFAIK there were very few AFV's that didn't use 1 piece rounds, where the shell and case with powder are a unit. Maybe a hand full of SP Guns. The Shell of a 105 contains about 10 kilos of HE, plus there is the weight of the shell itself, the case with the propellant charge could weigh another 20 kilos, so at 30 to 45 kilos per round you are getting toward the upper limits of what the gun bunnies can carry. The Big guns(150mm+ for the army) used bags of powder that are placed behind the shell with a firing charge. This is all 'rule of thumb' and can vary from army to army. T.
