Umm, i think i may have been that double barreled guy who shot you, my first ever act of banditry/kill was when me and my friend were running out of cherno and the only ammo we had was 2 double barreled shots, i shot someone in the legs and ran away laughing with my friend as they had some sort of weapon (i assume with no ammo since he didnt shoot back) and they got swarmed by zombies, i came back 5 minutes later to loot them and i think they had some sort of fully auto weapon, i can't remember 100%
