Antelope are my favorite big game to hunt, and I've poped a bunch of them. The meat from them has been both the best and worst of anything that I have eaten. It is all due to how you handle the kill and the buthering. For starters, they get nervous quick if they know you are around, so the adrenelin starts to pump. If you shoot them running or nervous, the meat isn't going to be good table fare. Do all you can to punch one that is unaware of your presence and has not been chased immediatly before hand. Once you get one on the ground, do exactly the opposite of deer/elk...DO NOT AGE THEM!!! Obviously field dress immediatly, but do everything you can to get it skinned, cut up, wrapped and on ice in 24 hours. As fast as you can cool it down, the beter you are. I always carry several ice chests with me filled with bags of ice. If you can't butcher it immediatly, pack the cavity with ice(leave in the bags) and add as often as required. Keep out of the sun, and at night hang if possible. I always have it on my ATV ramps at night to get the air circulating around it to help keep it cool. The best antelope I've eaten, I was butchering inside 1hr of the shot,and putting hot meat on ice. THat was the best meat I've ever had.
