I just came back from an awesome trip to Casper with a friend. I ended up with one buck and two doe antelope. We both had Mule buck tags but none were seen over the 4 days. I used a Rem 700 in 7mm mag w/Swarovski 4-12x50 and my Geovid. The buck are taken @245yds,doe at 382yds and another @200 running. I had some good luck with me.
