I always try and take the lungs out. I like the heart and neck. I have shot deer straight through the lungs, never touched anything else. In between ribs on in going, and out between ribs on outgoing. Made soup out of the lungs and didn't touch anything else. Deer didn't even know it was shot. It simply fell over. No drama, no flopping. It was a thing of beauty. Then there was that archery gut shot....
