At 10 yards simply drop magnification for clarity...easier on a " sensible" scope vs. a " hubble".... My 3x9x40s are paralaxed @ 30 yards & no problem shooting / seeing clearly @ 10 , on appropriate mag.
Edit: any 2x7x32 or 3x9x40 or 2.5x 10 will suffice, as smaller objectives give a better depth of field & all thats really needed @ air rifle ranges.
