My last years bull was at 370 I was prone on the bipod, almost level with him. Caught him quartering away, about the 8 or 9th rib back, the 180 PT exited out the left side of his chest. He was on the ground before the gun kicked off. As I was wading down and up through the snow and brush, he got up ran another 100 yards and was standing in the timber broadside when I came up to where he was laying. A shot through both front shoulders ended the hunt. I was shooting a 300 WM. Not an unusual occurrence.
