Annika:

Same thing happened to PatReeves on a HUGE buck on camera, last year (on his show). I would have sworn (as would anyone watching) it was a lethal hit. it ended up being deflected off the ribcage and only piercing the skin.

The buck was killed a while later, during gun season, and the wound was barely noticeable. Trail cam photos were also gathered of the buck shorty after he was arrowed.
