Re: cleaning my new Anschutz
My shooting coach, who owns several Anschutz's, uses a bore guide that replaces the bolt, a carbon fiber cleaning rod, and a copper brush with cleaning solvent. After brushing, she runs patches through, repeating as necessary. She has been doing so for decades without any harm to the rifles.
I use a bore snake in my 10/22 w/ Volquartsen barrel. Asking her about it, she said that bore snakes are a sure way to not harm the barrel, but they do not get the barrel clean enough for her.
She is also sure to emphasize that brass (or anything else that is soft) cleaning rods tend to become impregnated with the glass particles used in .22 primers and harm the barrel more than carbon fiber or even steel.
