Turrets can't harm a mob that is right next to it

[AlexiyOrlov]

If a mob is directly touching the turret, it can't hit him. Maybe it's a vanilla bug

It might be because the mob is so close to the turret that the turret's bullet is spawning inside the mob's hitbox, meaning the mob's hitbox doesn't detect the bullet.

It's like if you summon an arrow on your position, it does nothing, but if you summon an arrow ~3+ blocks above your position (outside of your hitbox), it will then collide with the outside of your hitbox and count as a hit.

The solution for turrets would just be to make the bullets spawn farther back behind the turret, so even mobs who are up close have less of a chance of the arrow spawning IN their hitbox (still won't work for mobs with gigantic hitboxes though, probably)
