Your prototype artillery ammunitions are great, but the prototype artillery requires you to be way too close for my liking.
So for people like me, it'd be amazing if you could add full artillery shell versions of the ammos, for use with normal artillery and artillery wagons.
Note: It seems you can load normal Artillery with the prototype shells, but they have limited range and are extremely inaccurate (veering completely off course from where the artillery is aiming).
