I've got a 45-70 bullet on my bench that I recovered from a doe that entered about 2" right of dead center on the south side end and stopped just under the skin at the north end. Went through a pelvis bone and still held together. Started out at 421 grains and ended up at 409 grains. Alloy was about 1:40 as near as I remember. Flatted out to a smidgen over an inch and was mushroomed back around the base. Purdy!
