I'm in the camp that says make sure the new gun has no machine chips in bbl, load and shoot the durn thing. Save the monies for cleaning stuff and the worry - for ammo to see what the gun likes and concentration on target and fun factor.
Of course I don't really clean bores on anything, unless mud, snow, rain...I do pipe clean chambers and extraction - this is the reliable part. This includes centerfire, even rifles.
Folks have a tendency to clean stuff that IMO is the wrong priorty. Barrel so clean you can eat off it...chamber extraction, trigger group never gets any inspect and attention.
Most folks use too much lube, especially with 22lr guns. all you want is thin film, you don't see it, barely feel it...all you need.
You get rained on...patch bbl to displace moisture, wipe off and check the exterior and metal to wood/syn - stock fit.
Voquarthsen ( sp?) recommends to NEVER run a bristle brush thru the bore. Pull a Patch Worm ( tm) or Otis (tm) with patch only from chamber to muzzle. This is IF rain, mud snow...
Look at this way, they have to put "something" about maintenance in the owners' manual...otherwise all there would be is lawyer-talk in the manual.
No offense, but folks worry too much about cleaning and lubes...the marketeers are so proud...
