Yes. Grant sells chamber stars that you jab through your jag and spin in the locking lug recess. Another alternative is Sinclairs lug cleaning tool, a dedicated tool that takes a double ended swab that Sinclair also sells. Chamber stars have lots of surface area, probably 5-6 little nubs that catch everything, Sinclairs have just two at opposing ends.
I use Sinclair's tool. I purchased it before the chamber stars became available so I don't know how they compare head-to-head. What I do know is that Sinclair's tool works well enough, much better than what I could do with Q-tips and needle nosed pliers.
Chamber stars don't need a dedicated tool but are more expensive than the Sinclair swabs, so you either invest in another tool, plus some cheap swabs, or just go with star-shaped swabs which cost a bit more.
Either beats Q-tips and hemostats hands down.
