I am currently having problem with calibration when shooting a target over 400m using Distant Horizen for viewing. Projectile trajectories stop rendering out the range of vanilla view distance, this makes calibration much harder, also harder to recognize hit or missed. However, adding view distance will significantly overload the computer. So I am requesting this feature to have a distanced battle with targets like dreadnoughts or AI cannons. In fact, I made a modpack The Adventure of Valkyriens that implemented world generated AI cannons, but I found it hard to calibrate cannons in a distance over 350m. Since I have done the calculation for cannon trajectory, the last step is to see where the projectile goes.

Here is the situation of the current trajectory, it disappears when flying beyond the view distance. Really grateful if you can manage to add this feature.
