My 3 .22RF's and my son's Stirling .22magnum get cleaned every now and then but more so if I've been in places where it's been very dusty. My BRNO .22 is a real bitch after I clean it as it needs about 4-5 shots to settle down and group properly again.
My F-I-L's Lithgow .22 single shot gets cleaned probably every 2nd to 3rd outing at the range. For some reason they just don't like being cleaned bore wise.
I do use WD40 on the barrels and actions and wipe them down after use though no matter what to prevent surface rust.
My .303,.270,30/06AI,.222REM,Ruger M77 22/250AI and my son's .30/30 Rossi and .Stevens .223 get scrubbed out after use and put away.
I use Sweets solvent to scrub them out and leave it in the bore for about 10 minutes before patching out.
