From what I could found, the weapon range is multiplied by the Combat Style range's multipliers depending on NPC. Most NPC's use the DefaultCombatStyle, which has a 1 multiplier. Translating game units into actual distance, for your average NPC, using default values, you'd get the following maximum shooting ranges: Hunting Rifle - 31 yards10mm SMG and Pistol - 12 yardsSawed-off Shotgun - 8 yardsSniper Rifle - 55 yardsVarmint Rifle - 46 yardsRiot Shotgun & Hungting Shotgun - 9.3 yardsLever-Action Shotgun - 24 yardsHunting Revolver - 23 yards.44 Magnum Revolver - 23 yards.356 Magnum Revolver - 12 yards9mm SMG - 16 yards9mm Pistol - 12 yardsCowboy Repeater - 23 yardsAnti-Materiel Rifle - 55 yardsAssault Carbine - 16 yardsLight Machine Gun - 16 yardsTrail Carbine - 23 yardsCaravan Shotgun - 9.3 yardsService Rifle - 55 yards Now those are some wild numbers if I'm right, and quite inconsistent on the developer's part. Realism isn't really at play here at all. A cell has 64 yards so most of the guns aren't even shot by NPC's from further away than 1 cell. The NPC's using DefaultSniperStyle get a x3 range multiplier so they'd be the only ones to pull this off.
