The furthest this rifle had been shot at distance with the night force scope was at 970 yards and it was only 2 rounds. Horrible mirage that day and not worth shooting anymore. I shot several groups at 800 to get everything dialed in and confirmed. Had a hunter come in and had him shoot at 580 yards and he was dead on. I even got the windage right that time. So yesterday my sweet Ami and I went out scouting and I wanted her to give this new set up a try. I found a rock with a little snow patch on it at 1050 yards and she let it fly. First round a tad low at 6 oclock. Second round dead on, perfect. Both shots would have killed an elk or deer. WOW. She was all grins at this point. My first shot was at 9 oclock and 6 inches left. Second round was dead on. hmmmm so I found out she held 2 to 3 MOA right. She said she thought I told her to do and since she tends to shoot left of center with my set ups, I am a left handed, she naturally held right. I corrected for wind the second time and was dead on. Windage is my weak point for sure. So the wind was blowing quartering to from the right at 9 mph with little gusts from 6-9. I used 5 mph and 15 degrees to muzzle. That gave me a .5 MOA. Clearly I was wrong. I was given the advice a little bit ago to use 45 degrees and actual wind speed. That would have been really really close to spot on for a hunting situation. Man, I am still learning this LR stuff and it is super fun. This site sure makes it easier as well. Thanks guys.
