It happens to every hunter. Some hunters fail to understand the idea of visualizing the angle of the animal or bullet exit. I've seen many hunters who aimed 'behind the shoulder' fail to realize their impact was actually going to be near the diaphragm instead of center of lungs because the animal was standing at a severe angle vs broadside. The cow elk I shot in 2022 was hit further back than I intended because her body was twisted in an unusual manner as she was looking over her shoulder at another hunter on the far hill. Fortunately, I was using a bullet that both expanded and penetrated through lung, diaphragm, and liver for a quick kill.
