lead buildup in cylinder...how to remove

[kmrcstintn]

I have a S&W 629 (.44 mag) that sees alot 'powder puff' and moderate loads in both .44 spl & .44 mag; 85% of what is shot through the gun is alloyed leadhead reloads from www.mastercast.net; the front of the cylinder walls have a buildup of lead;

upon its last cleaning (using GunSlick Copper Remover and a stiff bronze brush while inserting and spinning the brush over and over) I got out @ 40% of the lead buildup off and can't get anymore out

I think I need a stronger cleaning solvent or a specialized lead remover to take the rest of it out; what do I need? what will work? thanks

Are you sure there's lead on the cylinder face and not Carbon? I don't remember ever seeing lead on the cylinders of any of my revolvers.

In any case, Kleen Bore makes Lead-Away cloth which removed almost anything from your guns. It removes lead and carbon but DO NOT use it on Blue guns, Stainless guns only. It easily removes the heavy carbon ring from the front of the cylinder with very little effort. For removing carbon inside the charge holes just cut a very small patch and use a jag to clean out the charge holes. It's a really good product.

Birchwood Casey makes a similar product but it's almost twice the price and it works no better. I'm fairly sure Kleen Bore was the original.

yeah I'm almost certain it is lead...probably got fused on ever more while shooting jacketed softpoint loads during a session between leadhead only sessions; I also got some inside the bore of my Benelli Nova from firing Brenneke KO slugs (backup long gun for deer season in case I drop my rifle which might jar the optics)

thanks...I'll look for the Kleen Bore brand

Go buy chore boy copper scrub pad at the grocery store. Cut a strip and wrap it around a brush, a lot cheaper than the lead removal.

I use the Lewis Lead Remover, but I am going to try that chore boy copper scrub pad.

Take a magnet with you to the store.
Some of the new & improved copper scrub pads are copper plated steel shavings, and are hard on guns. Check them with a magnet first.

I have been cleaning stubborn chamber fouling out of revolver cylinders for at least 39 years using a bronze bore brush wound with 0000 Extra-Fine steel wool.
It was SOP when I gunsmithed for Army MTU teams in the late 60's.

Chuck the brush in a cordless drill, apply some Nitro Powder Solvent, and go for it.

It takes less then a minute to do all six holes, and they are gunsmith / factory clean when you get done.

It positively will not harm a gun.

For lead build up in the chamber use a chamber brush not a bore brush. They are thicker and stiffer then a bore brush. Browenells sells them. They do a good job for me.
