The reason I knew of an angled shot was of course, the exit appears to be right at the rear of the diaphram. It had to be one or the other, facing-on or facing-away. The last deer I shot with the #1 in 7x57, with a 173gr. Blue Nose at 2,500fps mv, made an entrance hole in the hide of 1", a 2 1/2" x 3" hole in the on-side rib cage, 3" hole through both lungs, smashed the offside shoulder, then the rear of the bullet made an exit 1/4" wide x 1/2" long with no blood on the outside of the hide, except for the larger entrance hole, looking just like your exit. Obviously, the old Blue Nose 173 was not designed for impact at near 2,500fps, but those long slim bullets still worked.
