Why such a heavy broadhead? You need to check out Easton's website for their arrow selection guide download. It is a neat tool. You don't have to buy Easton's but it definetly showed me a few things. If you have a 29" arrow and 190 grain broadhead then your F.O.C. (front of center balance) is way off. That could be a solution to your penetration problems. You could also try shooting a shorter arrow. I was shooting a 28" arrow and I chopped an extra inch off that I really didn't need. It makes you faster. Good luck.
