Long Range:It changes the chance to hit formula to (Perception-2)x16% instead of (Perception-2)x8%. In easy language, you have a much better chance to hit your target, using any weapon which has this perk. Scoped:Scoped is a weapon perk which adds +32% bonus to hit chance at a range of 8 or more hexes. At a range of 7 or less hexes the hit chance drops to 5%.
What means - if you have >5 PE, then making Scoped out of normal Hunting Rifle, it don't give you a shit, but even can make it wors.
Id like to know who added that to wiki
