I don't know much about African game, never been there, but that's quite a long section of core that got spit out of the jacket as the bullet turned/spun (note long chunk of jacket indicating turning) - having considerable weight & probably still good speed as it went through the lungs, but was too soft, material wise, to go through the rib & merely flattened, bounced off into the "chest meat"- somehow/must have gone between ribs, somewhere to get into the chest meat.

Judging by the amount of flattening of the non-pure lead core, it hit the rib fairly hard, hard enough to deflect and go in the 'chest meat' - how much damage did it make to both lungs? Killed quite quickly, indicating a lot of damage - that's the important stat for me. It must have had good speed going through the lungs AFTER going through the leg - that's pretty good for a non-solid cored softpoint. Would I use it again, maybe - depends on how it shoots, but going through that on-side leg sounds like good performance to me since it also holed the lungs and killed with one shot. That on-side leg bone is solid shot reserved normally for solids, isn't it?
