As a kid I (12 or 13 yrs) I could consistantly hit a dime at 10m w/ my Benjamin .177 pistol. Today I can hit a 4" disc at apx. 22m with the Crossman 1377 I picked up 2nd hand.
Wind is a much biggger relative fator with airguns owing to the lower velocities--you can really gage accuracy better indoors in a nice basement range. It is however a kick to fight the wind factor, too.
I've always just been an offhand plinker, but even low cost airguns are usually capable of good results.
