I'm no expert but it would be nice to know a little more about your setup. How much does your finished arrow weigh? How fast are you shooting with your hunting arrow?

If you want to get more penetration you will have to shoot a head with less resistance and stay away from the big bones. Ribs should not pose a problem but shoulders will stop an arrow. If you like the Rage heads go to the two blade they will give you more passthrus than the 3 blade.
