Two examples:
The Plasma cannons in Bob's vehicle equipment mod (All 6 tiers of the weapon, requires Bob's Logistics for armored trains or Bob's Warfare for Tanks) has a min_range set, yet seems to ignore it.
The Tank Artillery Cannon in Bob's warfare mod (MK2 and MK3 tank) also has a min_range set, yet seems to ignore it.

Perhaps I'm doing it wrong?

The plasma cannon code is a bit harder to quote, as the weapon is created in a function. But the fact that your tank can shoot at itself with it's artillery weapon should be example enough.

So, to make min_range apply to a weapon, the ammo needs to be target_type= position or direction, and clamp_position must be true on the ammo.
If you do that, the projectile's target position should be clamped to between the weapon's min_range and max_range.

In theory the ammo should already be set up correctly, since it can shoot the base game artillery ammo, and that ammo has the same issue.

clamp_position is not set on the base game artillery ammo, as far as I can see? ("artillery-shell")

I'll give it a try.

It works, but it breaks the artillery cannon/wagon
