Pitting is minimal on .22LRs due to the preservative tendency of the wax bullet coating. However, if cleaned and not preserved, they can rust. (I usually put a coat of Break-Free after solvent, but also store guns in a warm, dry place).
I’m not meaning to suggest a new .22 would be pitted, the suggestion was to look for abnormalities (my pictures were from my Carcano). All my rimfires get Bore Shine but I should have stock in Break Free with the copious amounts I use.
