>I saw a large mule deer buck shot with a 375 H&H using 300 grain Sierra BT's. The deer was standing @25 yards away, behind a fallen tree with a foot of new snow atop the fallen log. The bullet went through the freshly fallen snow, not hitting anything but snow, and stuck the deer in the lung cavity. When we skinned the deer we saw where the bullet had entered the deer sideways, aka keyholed, and the spent bullet was recovered on the opposite side unexpanded and had been flattened as if it had been laid flat on an avil and hit with a hammer. Just one incident doesnt make a pattern but an interesting example.
How does snow (or other material) affect a bullet?
