So I got the 4th Horseman from the raid this week and I've been leveling it up. It's a fun gun to use. But I finally got the return to sender perk (Kills with this weapon grant bonus ammo directly to the magazine) and it's simply not working. I killed 5 shanks in a row and got 0 shells back. So idk if this perk is supposed to be a Chance to get ammo back or if it's bugged and not doing what it is supposed to.
