I have no hunted them with a bow but my brother in law who has the TV show love of the hunt has. I watched him one year and he set up on some routine Pronghorn paths. In this particular area they ran a barb wire fence line through the day. I use this same tatic for them during rifle season. Yes pronghorn go every where pretty darn quick but I do notice that herds move the same way when pressure ed. If youcplan do use a blind put it out a month in advance. They pick things up pretty quickly as we all know.
