About 25 years ago a friend who was hunting with us on our farm said he ran out or ammo and left his spares back at the house. We were both shooting 270 Win. so he ask me if I had a couple extra until we got close the house. I gave him some of my reloads, I think I was loading 130 Sie. then at about 3200 fps. Later he killed a nice 6 point Buck and we were all looking it over and the only hit on it was across the left front corner of the chest. The bullet had gone between the hide and the meat without even cutting the thin membrane on the meat but tearing a patch of hide off about 7 inches across. The deer had been quartering to him and he had only fired one shot and it dropped in it's tracks. The only thing I could figure a shock wave from bullet energy had stopped his heart. This was about a 150 to 160 lb Deer.
