sorry old time .22 match shooter here...from the days when i shot on the ROTC rifle team, we never cleaned our rifles. granted this was with bolt actions rather then semi-autos which are somewhat less tolerent.
in my handguns, especially wheelguns, i always wipe down the action, especially the ejector star, but usually just leave the bore. if it was an dirty batch of ammo, i'll run a dry patch, once, down the bore.
