Hello,
Had a check though to see if this has been raised previously, couldn't find any topics about it. A few times iv found I'm hitting "structures" / "objects" with hit box's that are huge. Fire hydrants, news paper stands etc. and then recently had this issue with a "NPC" where I shot over the top of them but the NPC hit box was triggered so I made a short clip and slowed it, basic visual edit to demonstrate.
Wasn't sure if this was just a normal "hit box" issue or Resolution "hit box scaling" issue? as I'm playing at higher resolution / quality 2560x1440 window mode and running on an RTX3070. Although not hardware related. I know this might not be something worth fixing any time soon given the "Engine update" and rarity of shooting over/ around NPC's. but ay worth letting you know,
