Not a stupid question.. You are just trying to educate your self.. Never scrub you bore with anything dry. Always use a bore solvent !! Nylon brushes are great for a general, fast cleaning
of your bore. Shooter Choice all bronze brush for you bore size is a great brush. The bronze is softer than your barrel but stiff enough to get out the tough carbon build up in the throat
area out.. A big misconception : nylon is softer !! It is but if its used a lot it will wear your bore too !!! Here is some great info on barrel cleaning. http://www.6mmbr.com/borebrushing.html
good luck..
