I just hapened to have some free time and came across a post ( on another site) that said to NEVER run a brush down the barrel of a 22 cal pistol.. they say it will ruin the accurcy by taking the rifling out of the bore...now that sent chills down my back, as im a "clean nut" and always try to do the right thing.. I cant figure out how the soft brass brush would hurt a steel bore, but many claim it took away their tight grooping.***any comments on how to properly get the lead out?? thanks in advance for any info,,
