First of all congrats on what was obviously a very successful hunt. With regard to the bullet performance, I personally am really happy with a SP that delivers a pass through. More damage than a solid, yet still the benefit of an exit wound. That is why I use the TSX so often (unless I am using a Woodleigh Hydro) - and unless the target is a cape buffalo or eland, they are almost impossible to recover. I haven't used it, but the AB has a well earned reputation as a stoutly constructed bullet . What you describe sounds and looks like what I would expect from a TSX which would be pretty much ideal performance for me (well, not the zebra). I am confident that the internal damage was significantly more than a FMJ would deliver. With regard to your warthog specifically, he looks pretty dead.
What did everything between the two holes look like? That is what really matters. Were any of these long recoveries? What would you have preferred?
