What I did learn today was a lot of the little things I don't pay attention to at my normal 565-600yd mark, start to really stand out at 800. Like that group of ten I had 6 Hornady brass and 4 Winchester brass. It's pretty easy to tell which 4 were Winchesters from the picture. So if I sorted and stuck to hornadys I still have about 27MOA of elevation left in the scope. Might wait for a calmer day and give it hell at a bit further... I better get it done before the neighbors corn gets very tall though.
