RE: why can't I get a pass through???
What is your draw length out of curiousity?
And I agree with Arthur, heavier arrows may help some.
And paper tunining really doesn't mean much. The important thing is how do they fly with the fixed blades on them. Like said, improper arrow flight can suck a lot of energy out of the arrow.
And if you didn't recover the deer there is really no way to know for sure where you hit it. Just where you "think" you hit. It is pretty common for people to think they put a good shot on a deer only to discover it was not that great. Not slamming you or anything, just telling you how things are sometimes. It all happens so fast it is hard to be really sure most of the time.
My advice is if you are not happy with this set up try something different like a different broad head or arrow. Or go back to what you were using before. Just make sure they are tuned with the broad heads on.
And when you said it was tuned, was it tuned with the new arrows or the aluminums? You cannot just switch arrows and expect things to be the same. It is not unusual to have to re-tune the bow for those arrows.
