My heavy cannons have a listed range of 8700 and can aim most of the distance across the tavern (near the stubborn old man) to the far dummies
The cannon "thinks" it can shoot that far, but seems to explode on nothing.
My best guess is that the Hvy cannon's projectile has a max travel distance or travel time of 6000 units, maybe to do with the +dmg per range mechanic caps off at +100% bonus.
Can it be changed so that the dmg bonus may cap/curve off but the projectile keeps traveling towards it's target up to the towers full range?

Have to be careful not to aim it so the row of 5 dummies are in it's aiming zone

Can be aimed such that it is damaging nothing at all, at it will explode in the exact same spot
