Just got back from WY... and no we didn't go 10 for 10! We leave that to the real pros ha. We had 7 tags and came back with 5 prongers. My dad and uncle were the two to come back empty handed but my dad was too busy helping others fill tags and my uncle was too busy fishing!
Anyways, I pulled out my dad's .444 Marlin, took the scope off and made up some handloads a couple weeks ago. After five stalks (one of which I crawled within 70 yards of the herd before getting busted) I finally let the big sausage slinger roar and put a 265 grain slug into a two year old (incisor eruption) doe's spine. That was the loudest smack I've ever heard a bullet make upon entering an animal! That bullet is litterally twice as heavy as anything else I've ever shot a pronghorn with.
If I ever decide to use the ol' beast again on pronghorn... I'll be pulling off the iron sights and putting on a peep sight.
