I still use the toothbrush and cleaning rod method, too ingrained in the old school to learn to use a boresnake. The tooth brush is to clean off unburnt powder granules and the cleaning rod is for chambers be it rifle or handgun. Occasionally I run the rod through the bore but as others have said, the lubricant on .22 bullets protects bores pretty well. Even Anschutz, who makes top grade competition rifles, advises bore cleaning be done only intermittently. YMMV
