The simplest solution is to use low-magnification scopes. This is because lower-power models have greater depth of focus—meaning they are more forgiving than optics of higher magnification.
We can see this at work with a variable-power scope simply by setting it at low magnification and seeing how the close-distance focus is sharper than at the high end of the magnification range. This, of course, is why scopes made specifically for rimfire use are almost always of modest magnification, usually 4X or even less.
