I have shot several antelope with a fairly hot load with Hornady 130 gr SST. shot one through the boiler room at less than 100 yards, the exit hole was big enough to put my thumb in but the lungs were mushed up good. Another at well over 300 yards, took a few slow steps and fell and died. Same deal. bullet passed clear through. So I am not sure how these detonations occur. Maybe white tail are tougher than goats.
