Jeff I'm not nit picking anything , I have not shot a deer in the last ten years that has made it out of my sight before dying. I lied one did.
I shoot them close (under 20 Yrd's) with 125 grain thunderheads. I have shot them facing me, broadside, quartering away and every way in between ,I'm not picky on shot angles.
I shot 62lbs with heavy arrows and the results are measured by how far my arrow sticks into the earth on the other side of the deer.
Never had one not go Thur and bury into the earth.
Just maybe you are not doing something right.
