As has been said, you can use a brush if you feel it is necessary as long as you use the correct brush and give it that little CW turn before pulling it out.
Some say it is completely unnecessary,,, but some say a lot of things.
Our late friend @Flehto used a brush on an inverted/muzzledown rifle instead of wet swabbing between shots, this broke up and allowed to fall out any caked on residue. It always made sense to me, even of the muzzle down thing isn't practical for everyone. I recently have been doing similar on a certain part on a particular unmentionable, dry brushing dry residue/carbon,,,, works much better than turning it to liquid 1st then trying to mop up.
Get the propper tools and try it for yourself.
