My greatest passion in hunting is long range marmots. The goal this year was to break the 3/4 mile mark, 1320 yards. It's a 3 hour drive from my house to my shooting place, and another hour to hike in. I went in Friday night to be ready the next morning when the air was most still. For a couple hours yesterday and this morning the air currents were steady, resulting in a .75 MOA wind drift and a slight down draft worth .25 to .5 MOA, with an occasional gust. By mid day the clouds would roll in and the wind made it impossible to shoot long range. This morning after several near misses I connected at 1332 yards, and later rolled one off its' rock at 1393, but it made it down a hole... no picture so not an "official" hit. I'll have to try for his buddies next week.
