Killed a mule deer in western nebraska 2010 at approx 350 yards. Longest shot so far. Would not want to try anything further till I am finished with my rifle upgrade project and get some handloads that my ruger likes.
I had just finished sighting in my 700 and the following weekend my hunting partner and I were out glassing for Coyotes. My buddy tells me he sees a P-Dog way out there, so after a few minutes with the range finder and getting set-up, I let one fly.
It was too hard to tell if I connected or not, so we walked out there to check things out and sure enough I had connected with the little bugger! My best ever long range shot to date!
