I used to practice quite a bit out to 1200 yards. Will be practicing out to a mile possibly soon. But at this point only out to 800 yards when I can. In any case the farthest shot I've taken on big game is 125 yards and I like it that way. 500 yards is what my set limit is and I'm not excited about pushing it out that far. Just too many variables. On varmints I'll push it as far as I can get a clean 1st shot kill. I consider my 400 yard coldbore headshot on a rock chuck with my M4 the best shot I've made.
