Dave37,

I feel for you. I hate situations like this. I can assure you, however, and I'm sure you know, these beasts are a hardy lot! Do your very best to locate him. Stay postive under all circumstances. A postive attitude is critical-it will keep you looking when things aren't going your way!

Do not blame your bow or broadhead-sounds to me like you have plenty of both to get the job done. Did you shoot low enough to miss his chest cavity? Did the arrow stop after hitting his opposite leg? From 15 yards, I would think your arrow would have blown through his chest had it only hit chest matter.

Keep us posted....
