Reticule turning red

Obviously we all know the reticule is supposed to turn red when placed on an enemy what i am wondering is in multiplayer at what range is this? I’ve noticed at times it doesn’t turn red it confuses me at times i don’t know whether to take the shot as it has me thinking is it lag or what.

Depends on the weapon and whether you’re smart scoped or not.
