Get SCA arrowheads. You know, the geeks that dress up in armor and play fight, they make REALLY heavy broadheads for that. Of course they are not sharp at all, but a half hour with a grinder and they are perfect. I have one on my new arrows, and its around 345 grains at the tip. I think about 600-700 or somewhere overall. The thing is, Im shooting a 45# bow, and that arrows is flying better than any other I have at hunting distances. And its by far the hardest to get out of the target, it blows through almost everything, boxes, hay, tree bark....
