Rimfire priming compounds are abrasive. I used to shoot NRA Indoor Four-Position Small Bore in a tri-county club league. The only reason the nice Anschutz match barrels would ever need replacing was a worn area at 6 o'clock, right in front of the chamber. A gunsmith said it was where the abrasive primer residue would fall and eventually cause wear.
As far as cleaning rimfire barrels, some of the competitors cleaned after every match. Some, once a week. Some, at the end of the season.
I usually just run a dry Bore Snake through my rimfire hunting/plinking rifles after I use them. I did experience a leading problem once. It involved a Ruger 10/22, cheap Winchester Wildcat ammo, and a sustained high rate of fire.
I found that particular ammo (and some other "promotional" grade ammo) did cause leading in other .22s too. The cheap lead bullets aren't copper plated or copper washed like better ammo. Plain lead bullets (lubed) are fine in standard velocity or target loads, but tend to cause leading in high-velocity loads like Wildcat. I won't use it at all any more.
