!st of all Congrats,could you tell if all the blades opend up because all I can think of is that the BHwas deflected once it enterd the deer as in one of the blades didnt open and thus causing it to deflect off off a bone or he bucked when hit but the main point is you killed a deer and harvested it good job.....Nothing like a guy/gal 1st cb deer,got my 1st Oct 11th.......
