First step is to make sure the bow is tuned, if the arrow isn't flying right you won't penetrate. A couple of simple tests:

- shoot a BH anda fp of the same weight, shoot them from 30+ yards. Do they hit close to each other?

- Hang a string down your target. Start at 10 yards shoot at the top of the string. Now back up to 20, 30, 40, .... AIM WITH THE SAME PIN EVERY TIME. Are your arrows hitting verticle or are they moving over one way or the other (or both).

- Put the arrow BH tip on a table and spin it. Does either the BH or the nock wobble at all? Shouldn't

Ifany of these tests fail, then you have an out of tune bow. A 55 lb draw bow should have no problem getting through a deer. Baby-G isa "hard" cam so you might also want to check the spine of the arrow (I don't know anythign about your arrows to tell if you are close on spine).
