My Weaver V-24 is the same way.Lower powers it' s very clear. At the high powers it' s blurred some.That was using it on a 100 yd range.I haven' t tried it at a longer distance.This is the first scope I have bought with this high a magnification.All my others are 3x9' s or 2x7' s. It must be the characterists of these scopes.
