Being able to distinguish .22 holes with a spotting scope @ anything much over 300 yards is the province of some very expensive glass, if even then.
As to the op's question regarding Konus scopes, I have a buddy that has one and he likes it a lot. Of course, he also swears by his Barska optics which makes me question his discernments concerning what constitutes a good scope. So, nothing of value from me re Konus scopes as I have no first hand experience with them.
