I believe if they are made of cotton wouldn't the patches cause wear on the sharp rifling edges? It is recommended to push the patch thru the chamber end to the muzzle. I'm not sure, but cotton is supposed to be naturally abrasive, which is why it's not recommended to clean eye glasses with cotton. Just a thought I pondered while cleaning my new to me HiPower.
