Again, can be explained by SD.
An arrow has a way, way higher SD compared to a hunting bullet so can afford to hit it's target with a far lower speed to achieve the same penetration. Plus an arrow is not designed to deform like a bullet so it's SD doesn't change inside the target as per ChrisW's comment.
