I have an antelope hunt coming up in a couple of weeks and I am looking for any advice that may help me. Up to this point my longest shot was on an elk at 330 yards(Its in the freezer). This hunt I will have opertunities to shoot between 300 and 600 yards. 600 is my limit at this point. I have practiced on paper and gongs out to 600 with good results. I have not had much practice in the wind. I will be shooting a rem 700vs in 308win with a bushnell 3200 elite fixed 10 power on it. My load is hornady 165 grain sst's starting at 2400 fps. I have a drop chart taped to my rifle that has windage estimated for 10mph and yardage out to 600 yards. I'm considering taking sandbags. I will hopefully be shooting prone but may have to shoot off stix because of high sage. Any suggestions or tips you may have would be appreciated.
