I wouldn't neccessarily expect passthroughs every time, but your setup will do quite well at killing deer . Just stay away from the dense shoulder muscles and bone, as that will impede penetration. Your choice of using a 2-bld / cut on contact head is key. There was an article written in Traditional Bowhunter Magazine a year or so ago that chronicled the low poundage outfits of several women. They had no problems killing deer and elk with their high 30's to high 40's poundage longbows.
