I have had a huskimaw since they came out, I've made kills at 350, 550, 500 and 650. I haven't had any issues with my scope, dial it and if no wind, shoot. Haven't had to adjust for wind but the wind dots are in the eye piece. Only problem I had was finding a place to sight in at 650 yards, if I had to do it over, I would drive my gun to Wyoming and have those guys set it up for me. I went through enough ammo to pay for them to set it up. If not huskimaw, I would consider night force out of Idaho.
