The rifle has shot GREAT! I took around a dozen marmots over 900 yards, the longest 2 being 1108 and 1156 yards. I was trying to get one at 1380, but he would not stop moving. When he finally disappeared I fired at marmot sized rock where he had been standing, and hit the left edge of it. Next years ground hog goal is 1320 yards, the 3/4 mile mark. What's left after that but the mile mark.
As for the ART reticle, I have not used it enough to say much more than it seems to work fine. Mostly I am still twisting turrets... old habit.
