Well,I'm going against the grain here, but I hardly use brushes and rods anymore and have nine bore snakes.A spritz of wd40 [just a little] slicks a new bore snake right up,and prevents jamming.Jamming usually occurs when you try to 'scrub' by grabbing each end,and pulling back and forth.DON'T do this.DON'T ask me how I know...it's easy enough to clear though.You have someone else pull,while you push, on an appropriate size rod
I have never had a bore snake break on me,and I have used them since they first came out,but I HAVE had the brush part wear out,from strong solvents,and LOTS of use.I just bought a new one when ever they quit getting a gun clean ,and used the old one for black powder.I label those 'BP' and use them for .45-70,.45 long Colt, .38/.357 .44 ,.36 and .31 Remington percussion revolvers.
