175 grain Tiger Shark.
It wasn't a pass through, but I hit the humerus and it glanced back into the rib cage. It clipped the back lobe off of both lungs. The blood trail was impressive! It made kind of a funny scraping noise when I hit her.
Notice the triceps muscle sliced off the bone. You can see the entry hole in the rib cage is back farther than I would have thought based on where the arrow hit. There was only one hole, but it was large and low, so the trail was bright red and pretty short.
I sharpen with a jewel stick and finish with a few strokes on a set of crock sticks. They are scary sharp! This is the first year I've used them. So far, I'm impressed.
