Sorry for the late reply. Have not been following this thread. My recommendation for a scope power for 25m to 100m is something in the 4x-16x range. For 100m target shooting I set mine at 12x. About 40mm objective diameter will be all you need. Main feature for .22 is to get a scope with either adjustable objective (AO) or side focus/parallax adjustment; with either of these you can dial out any parallax problem at any distance you are shooting. As mentioned on another post, Hawke scopes are very suitable - best place to find them is often with air gun dealers.
