Pronghorn as related to goats should be treated and cooked as such. Medium rare is about the most you want to cook it quickly like a steak or burger... or slow roast it.
Careful prep to not touch the scent glands on the back legs and touching any meat should be very strictly followed. This taints the taste of the whole thing!
I've seen many people grabbing and handling the rear legs touching the scent gland while field dressing, then while gutting and/or cutting open the pelvis or chest cavity having those same hands touch meat. This scent/taste is now in the meat. This is a common reason people don't like the taste of antelope.
Antelope like all animals taste like their environment. A lot of antelope in northern Colorado and Wyoming eat a lot of sage and reek of it. Personally I won't hunt antelope north of US Highway 24 and I-70... to much sage. Antelope that graze along side cattle are usually pretty tasty.
