Help with weapon range - is there a maxium?

[elfstone]

Hi,
I'm just starting to learn how to mod using the Plague Gun tutorial. https://rimworldwiki.com/wiki/Plague_Gun/Introduction
I tried to change the range of the plague gun, and noticed that when i put a rather high value (e.g. 80) for range, it will not display the gun-radius in game, and won't shoot at all. If i use a range of 60, it will not display the gun radius, but shoot, and when i use 40 as range, it works normally (shoots and the gun radius is displayed in game).
Is there some kind of maximum range for a weapon the game can handel? Or am I missing something else?

Thanks for the help :-)
