Something I took notice of was that the range of the main cannon of this mod was 300 but the range of the shells themselves is 30. So no matter how far the main cannon shoots the shell will only go 30 and hit the ground. Is there a chance you can edit the shells with this mode to have a matching range of the cannon?

I think it is possible, but I will be adding custom ammo instead

ok, that works. I just felt it was not taking advantage of the main gun range whereas the machine-gun fire was using all of the 75 range of its gun. So modded ammo might be the best to fully use the main guns range advantage.
