That should work - if you are talking about cleaning the 'flash channel' right under the primer.

And actually if you are not shooting the really hot primers you really should not be getting much of a build up in the channel.

The drill bit things just seems to help clean the debris out as you are turning.

When my Encore got more blow back, my breech plug was wore out. The Encore and Omega have the same plug. I think you will see more blowback when you clean it out????

The Oral-B dental floss has small amount of abrasive quality. Put some solvent on the spongy part of the thread and run it through 8-10 times. It cleans my Omega plug great.
