There is no need to swab between shots, but you do need to remove the carbon from the flame channel of the breech plug. This you can do with a 1/8" drill. I have old worn chucks here, and i put the drill in a chuck and turn it by hand. If you allow the carbon to build, you may need to start the carbon removal with smaller drills, and finish with the 1/8". Doing this every 10 shot or so, keeps it simple.

Any solvent including Hoppes, will work when using BH. Birchwood Casey bore scrubber is what i have been using as of late.
