I've ranged deer out to a little over 1300 yards on flat terrain with the Bushnell. I haven't had a chance to try it any farther on game, but I'm confident it'll go beyond that. It's pretty easy to aim above the animal, and come down until you get a consistent reading. I've used the Bushnell to get first-round hits on 8-12" rocks at 800 yards, 983 yards, and 1130 yards. It obviously can't be all that terrible if it enables me to hit the small targets that I'm aiming at at those ranges. It's got some features that allow you to select the farthest item within the beam dispersion, or the closest, which helps to mitigate the problem of having a larger dispersion than the more pricey RF's out there.
There is no question that the Bushnell and Leica 1600 are at the low end of the price range when it comes to RF's that will work on game out beyond 1000. The more you're willing to pay, the better a product you get. The guy asked for the cheapest RF's that'll get out to 1000. The Bushnell is around $750, and the Leica is around the same price (although the Bushnell is a RF/bino, while the Leica is just a RF), the G7 is a better unit, but costs twice as much at $1,500, and the Terrapin is even more at $2,000. If you want to get an even better RF, you can look at the Vectronix PLRF10 at ~$3,000, or better yet would be the Vector 21, but you better be prepared to pay $10,000 for that one.
It all just a matter of getting the best RF performance that you can afford.
