I've had pretty good luck with a Sportsman's Warehouse special Vortex. I think it's the Ranger 1,000, and it'll hit rocks at up to 1,200-1,300 yards, trees at 800-900 yards, and critters nearly that far (if they're big enough). It's been going strong for three years now, with no apparent degradation in performance. For the price, I'm not going to complain!
