First of all with what you have stated your set up to be I would say you have plenty to kill a deer. A pass through is not always because that person has a high draw weight it has alot to do with where you hit on the deer and how many bones you hit on the way through. I have only had one pass through in all the time I have hunted. My set up is 66 pound draw on a buck saber bow beaman carbons and 100 grain muzzy fixed head. Second you just have to watch what you are doing when you start to field dress. When you get to the hit area you should be able to find the rest of the arrow assuming that it didn't work its way out.
