I thank everyone for their input!
JRBSR had some whizz-bang calculator thingamabob that he was able to plug in my stats to gauge what my variances are, the end result being a 35yd shot shooting like 34yds.
I get the concept of using a 3 dimensional aspect for shot placement, factoring in the location of the vitals inside the animal based on angle of shot.
This group is amazing! Good Luck and God Bless!
