I'm a little surprised, you don't have a exit with this on oryx

I believe it was because the shots were both quartering shots and traveled through a lot of animal.
The first was quartering towards me and I broke the left shoulder at ~160 yards.
Follow up shot to the left ribs through to the right shoulder at ~175 yards.
If they were closer shots, probably would not have been recovered.
