RE: How to scope a .338
A 3 - 9 X will be all you will need. With saying that there are a couple af manufacturers that offer 3 - 12 X scopes. I really like the idea of having en extra 3 powers for the far off shot and still having a 3 power for that close in shot. The 4 -12 X is far more common though. Bushnell offers an elite 3200 in 4 - 16 X.
