I bought a weaver Grand Slam a couple of years ago and the windage adjustment barely worked. i did manage to get it sighted in but was very erratic in the way it moved. Son hunted the rifle a few days and killed the deer he shot at. This year windage was off 3" at a100 yards wouldn't adjust. Went through the warranty return process and had to return to a bushnell repair center. They sent it back saying it was in spec after testing.
If a scope that has no windage adjustment capability is within spec I will never buy any optics products from them ever again.
