Been cleaning (soaking) this cylinder every week with Hoppe's & a good scrub every other day with a 50 cal stiff bore brush.

Been about 2 months now of use & cleaning after one match on Sat (about 90 rds) still can not get this build up out

What do you gents use to get this build up out once its out I think my regular cleaning will keep it from builing up, it was a used pistol hence the build up.

Tried Gunslick & RB also, trying to avoid a nail head or other harsh tactics.

Depends on the caliber. For .45's I use a .475/.480 bronze bore brush on a short piece of cleaning rod chucked in a drill motor and some Hoppe's. Takes just a couple minutes to remove the carbon/crud. .38/.357 gets a .40 bore brush etc.

I had a tough one, a Model 19-5 that had shot a lot of .38 rounds. The fella who owned it never cleaned the cylinder very well. I used Hoppes and Break Free with a Dremel tool, alternating between a Dremel nylon brush and a Dremel brass brush. It took a while but cleaned up nicely. I finished by polishing the holes with the Dremel and a soft buffing wheel using Flitz polish.

What is the build-up? Is it lead? If so and the cylinder is Stainless Steel, soak it in a 50/50 mix of white vinegar and peroxide. No more than 5 minutes should do it. Run a brush through to give it a final cleaning.
If it's a blue cylinder, try wrapping Chor-Boy (not the steel version, use the copper version) around your 44 caliber brush and make a few passes (from the back of the cylinder to the front). Plasitic jags with soaked patches of Hoppes should also work. Put enough patches on top of each other to get a good and tight fit in the chamber.
How to stop it? We need to know what it is first.

I use an old bronze brush covered with 0000 steel wool and spun with a drill....

Lewis Lead Remover Kit, or lead-a-way treated cloth cut into patches.

Install your bore brush in a drill, watch the chuck against the frame. It helps to know if your working on lead or carbon. You can also wind up a piece of Chore Boy copper scrubbing pad on your cleaning patch end piece. If you are careful with the chuck it usually won't damage the male threads.

629 (Stainless) the material is a carbon ring not Lead or Copper

The vinegar solution works fine for lead but not the carbon.

Ate up one 50cal bore brush over the last couple months cleaning it by hand (NO Drill yet that may be the answer though)

The carbon is really burnt on there, chipped a few hunks off with a alum cleaning rod.

Thanks Gents

Many are reluctant to use a drill motor. I have a piece of claeaning rod I cut off just to chuck in a drill motor for cleaning chambers. It gets used before every match. Does something that can be difficult, in minutes. It helps to squirt some Hoppe's or Kroil in the chambers and let it soak into the crud before using the brush. It's also easier on the brushes than running them by hand.

Brownells sells a cleanining rod adapter: 084-116-362 CLEANING ROD, SMALL ARMS - Brownells That works great in a drill motor.

I agree with Chief38 on the Lewis Lead Remover. Doesn't take long to do the job and without the risk of over zealous use of power tools.

If it really is carbon and not lead, try KG-1 carbon remover. If it's lead, use a Lewis Lead Remover on it!
