Thread: Repeat until patches come out clean

Thanks Guys for your feedback on this one.

Have now run 30x patches with JBs through each of the barrels, following on from what seemed like endless bronze brushing. Patches still always dark black after a few strokes. Tried JIF as an alternative. Patches very light grey. JIF either isn't removing the same amount or more likely has a white pigment that JBs lacks so that the colour is masked. There looks to be something in what Munsey said in that JBs colours up very easily.

Anyway it is easily checked by looking at the muzzle on the chrome-moly barrels. Despite all the cleaning, both bores just inside the muzzle are still dark grey - it looks to be bluing as Druid indicated, polished up to a mirror finish - and probably is dark the whole way down, I don't have a borescope to see. If it was really back to base metal it would be bare metal silver shiny. The bluing service I use does not plug the barrels. If I ever get another CM barrel from new I'll look to keep the bore in the white as a visual aid to cleaning.

It seems clean is never actually clean, just somewhere on the continuum. Is the powder all gone and just bluing left; I can't tell.
What I do think I am safe in saying is that the cleaning regime description I kicked this post off with where patches come out clean may not be because the bore is in fact clean, just at the limit of the cleaning method being used. I now need to find the minimum cleaning routine to bring each bore back to a level where I get another 30-40 shot accuracy but I won't be looking for clean patches to tell if the job is done anymore.
