We were out hunting this morning and was able to hit an elk. We had a quartering shot at 50 yards. We found the arrow and it had about 16 inches of penetration. There was bubbles in the blood which comes from the lungs. We tracked the bull for about a half a mile and left him and backed out not wanting to spook him. The cows he was with didn't follow him and the bull was not able to go uphill. He started uphill but turned back after about 20 yards and continued downhill. He went into the thick pines and we hoped he bedded. We are going in to get him i was just curious what you guys thought? Will he die?
