I would add something :
.22lr.recoil is negligible, but you can bet it will be enough to emphasize all the shooter's faults and wrong wind evaluations, even at 50mt.,not less that any other caliber at any distance_
a quality rimfire rifle 22lr. w.quality ammos is intended as a one-holer at 50meters, therefore any group opening will be only shooter's fault_
if the rifle/ammo combo don't perform as above at this distance, aside the shooter's proficiency,the shooter will invest his time&money training himself behind a low-quality equiment, w.debatable gain_
about upper distances, the effects of all above will utterly grow, of course_
(scoped or not, don't matter)
