Just 1 problem... Heavy Arty doesn't use shell casings. It is mearly a war head ( the round ) put into the tube followed by bags of propellent charge. The number and type of bags used, combined with the elevation of the barrel, dictates the range of the round.

Someone from Lewis would say that.
Much of the arty in Il2 used rounds with cases, so this mod, although not all encompassing, is still pretty good.
