Thanks for the advice, heading up to Wyoming this season it can be very windy up there.I would look at the 6.5PRC or the 6.5x284 to run high BC bullets fast to help with wind for pronghorn. I have a 6.5x284 and have killed 2 antelope, multiple deer species (Mule, Whitetail, Blacktail), caribou, and elk with it. But specifically to your Antelope question....think about the wind if you are shooting more than 200 yards.
