I may not clean the bores of my .22's every time, but like others I try and at least wipe or swab out the action. Particular attention is paid to the breech face, feed ramp, extractor slot and bolt face on rifles and autoloading pistols. For revolvers I'll run a couple wet & dry patches through the chambers. Some brands of .22 ammo are just filthy and waxy so I like to get that junk out of the action.
