work ok to 300 meters
I have used them for military silhouette shooting in North California. We shoot from 200 to 500 meters. I found the accuracy fell off after 300 meters and I switched to SMK 168's. The privis are not as accurate at 100 or 200 or 300 meters as the SMK but they did the job. For a plinking round or moderate accuracy load, they are fine. For precision work, not as good.
