There are many makes of copper plated .22lr bullets, CCI Mini-Mags, for example. I have not experienced much fouling from .22lr bullets, maybe because they are so small...I dunno. Plus, there is very little powder in those teeny cases.
Most of the manuals I've seen from .22lrs say to just run a patch with a small bit of solvent and then a dry patch. The higher end barrel mfrs will void the warranty if a brush has been used.
So, I'm with Tango and others and don't be anal about your .22lr barrel. I bet if you see the same guys that only use a bore snake shooting a .308 for example, they will break out the whole cleaning gear for those. Pucker up and don't be so anal with your .22lr rifle.
Skullcrusher, you are evil, sick, demented, twisted- and my hero!
