I feel your pain. I have shot a decent number of deer with compounds and rarely ever got a pass thru. Heck I even shot a buck this year with a tusker concord and hit it right in the shoulder bone(accidently of course)and to my surprise, it didnt penetrate much at all. The arrow stuck, and he ran/walked off with it. I saw the deer 2 days later no arrow in him, but with a limp. Yes I tune my equipement. I have only shot 1 deer with a trad bow and I only got 1 entrance hole on a quartering away shot. I read storys all the time about arrows going thru and sticking in the ground 10" on the other side. Not calling anybody a liar, but either they hunt some soft ground, or they dont know 10". I can shoot at the ground and not hit an animal and not get more then a few inches of penetration. My latest setup is similar to yours, same arrows with 250grs up front out of a 45lb hoyt buffalo using the concords. I sure hope I start getting some of those amazing pass thrus I read about.
