Update:
I know a couple peopple asked me what he scores and until today I had not measured. I stopped home from lunch as my package arrived from WY and after getting the meat in the freezer I put a tape to him......

I printed off the P&Y scoring sheet and took my time measuring him exactly according to the guidelines and came up with the exact same score all 3 times....69"Gross P&Y with only 1/2" deduction side to side which makes him a 68 4/8" Net score.

Not sure if most Pronghorn Antelope are this symmetrical but he's almost identical side to side with 1/4" difference in total mass, and 1/4" difference on one prong.
Lengths and most mass measurements are identical.

So at 68 4/8" Net he is the first official Pope & Young animal I've ever taken! (P&Y minimum on Antelope is 67")
Not that the score means anything in the grand scheme of such a great hunt and beautiful animal but I thought that was pretty neat to find out, and a bonus.
