I'm guessing you just watched Drift0r's episode on the Tac-19. What he failed to mention is that the Tac-19, for some reason, never reaches that really low 10 damage. So it's effectively a 50-30 damage shotgun. So yes, you can get a one hit kill with it at long range. But pellet spread makes it unlikely.
