A friend took these pics and wants to get an Idea on the score. crappy pics but...

If the right side matches the left I would say you have right around an 80" antelope there.

Of course I'm no where near an expert on it, just a guess on my part.

somewhere between 70 and 90. Need a front or back view to hone in.. Looks nice and heavy.

Clueless about a number here, but eyebrows raised in appreciation

Looks huge and heavy, bigger in each picture = 83+.
