Finally got the Grendel out to 800 yards. It’s a 4 shot group because I lost the first shot, not sure what I did wrong. I think I didn’t check the level. In any case, I missed the steel so I stopped and setup again, checked my numbers, dialed, checked the level and put 4 in a 5.01 inch group at 800. I over comped for the wind and hit about a half MOA left. I set my zero stops for 200, my main zero for 400 and dialed from the 400 yard setting. 140 grain Berger VLDs and the powder was A2520. Not bad for an AR!
