Well I got this...
With this M1S 300 Fireball...
With the smaller of the two hollow points...
He ran 10 yards. I couldn't tell it was hit with anything.(I looked for a wound, but didn't look hard enough I guess) For all I know he could have ran into a tree and broke his neck. It was broke. But that is where I was aiming Mid neck, 85 yards. I always aim at the neck if I can. Even with my cross bow.
