Maybe the blades got dulled somehow. Shot in a target, corrosion from moisture(you can' t always " see" anything like rust, but they may have started to corrode, or maybe just a freak batch of bad blades. The odd-shaped, torn-looking hole has me wondering about the broadhead performance. If it was not a clean cut, he wouldn' t have bleed quickly, and probably wouldn' t have dropped much on the ground either.
It' s hard to say what happened. Sounds like it was a good shot and he should have been down in 100 yards or less. Saying that, I' m sure stranger things have happened.
