Tough go on the tracking and coming up with one.
The animals are so similar and can certainly be tough to differentiate between individuals.
That shot placement diagram sure will play in your mind for some time to come.
Thanks for sharing your story.
I had memorized the shot placement diagrams of the species I was after + several others. But I only memorized the vitals. I didn't think that I would be trying to take shots from this angle to the neck. Clearly this was not enough and one should memorize the whole animal. This was another lesson learnt during this trip.
