I just got back from my high country mule deer hunt. I took my 13 year old daughter with me and she was a trooper! We parker the truck at the trailhead at 8500 ft and climbed to 10000 ft and set up camp. We located the group of bucks I had scouted in the summer and tried to get a shot. I honestly couldn't close the distance any closer then 1k yards the entire first day. they were bedding on a bare hill side with no cover to conceal my approach. we waited and watched them until dark that day hoping they would feed closer as I wasn't confident much past 800 yards on game. they didn't feed closer. we made a plan to hike to the closest group of aspens the next morning in the dark and hopefully they would present a shot. they did. I had my buck at 724 yards at a 30 degree incline up. I entered this along with pressure temp and altitude and dialed up for the shot. I put my daughter on the spotter and told her to watch my shot. she did. my first shot hit high and she called the correction and the next hit home. I couldn't have done it without her. I'm still boggled as to why I missed the first shot. I hadn't done much shooting at such inclines and that is all I think it was. the high country definitely exploited my weaknesses. this is my first long range kill. I couldn't be happier to have shared it with my daughter.
