The method you are useing has worked for years " as long as you are carefull", Ive seen something new on the market though!, it is a protected cable with a quick disconnect head for the brushes and jags. You put the cable down the muzzle then connect the brush at the action and pull it through, sounds like a pretty good set-up, only problem is Ive seen it advertized one time and havent seen it since!.
