I have been using the new terminator 125gr 3 blade serrated fixed blade broadheads and they are evcellent!! I took now a really nice 6pt and let me tell you it brought him down fast!! It put one heck of a hole in him and he ran no farther than 25yds. I would really reccomend trying these broadheads.

What organs did you hit? That may have corelation to how fast the animal went down. Just a thought.
