Atlas, my apoligies if I upset you with anything I said earlier. That was surely not my intent. And, thanks for the geometry lesson.

The shoulder hit that took my buck this year was the large, flat bone with the ridge. I am referring to the same bone? The arrow passed through it, and went out the other side of the animal, just back of the opposite front leg. Now, the arrow was still in him when he took off after the shot, but it was in fact a very lethal shot, taking both lungs. I was using the new Rocky Mountain Snyper XP3 mechanical. He made it a mere 60 yards before expiring. Guttingrevealed a double lung kill.

And for the sake of accuracy, I was shooting a Bowtech Allegiance set at 65lbs and 28" draw. Total arrow weight is 360 grains. I don't consider this setup ideal for this type of hit but it worked this time. Maybe I got lucky.

For my sake, I included this image with the bone I hit circled. This is the same shoulder bone everyone is referring to?
