I would have taken that shot with confidence with an 80ELDM. I would expect it to work well. We may end up differing in that opinion. Unfortunately answering the question requires speculation until we find a good sample size of experimental boars to test.
I haven't seen any results in the animals I have shot that would lead me to lack confidence in that shot. The 80s have penetrated well and broken big bones on everything. The biggest pig I have shot with them was probably about 40-50kg and the bullet penetrated fully through both shoulders hitting some bones and was under the skin on the far side.
