Toot - I respectfully disagree. 100 yds - maybe. But not much more. A well placed lung shot punching a 50 cal hole through both lungs even with the lowly but effective round ball will put most any deer down within 100 yds.
I too hunt the heavy woods and laurel patches of PA. And I am relating my experience fromeasily over 100 deer shot by myself and friends/relation that I've helped recover. Now I will grant you that a poorly placed shot or a single lung hit will increase the distance a deer will go if pushed too quickly. That is why my earlier post stated that if you don't see the animal fall, give it some time before persuing. And track slowly and carefully.
