I am working on fixing a similar problem. I found this link informative: Chapter 7 - The Cast Bullet Nemesis - Cast Bullet Guide for Handgunners - Glen E. Fryxell

I use Chore-Boy, a cleaning jag, and a small patch of cotton cloth. I cut a small hole in the little square of cleaning patch, and put the threaded end of the jag through that. Then I cut a piece of Chore-Boy, and fold that up, and put the threaded end of the jag through that too.
Then I feed that into the forcing cone end of the barrel, and put the cleaning rod into the barrel and screw it onto the jag. I then spray some lead cleaner or some such cleaning fluid on the jag.
From experience, I know just how much material to use to get a tight fit, but one that will pull through the barrel with a good amount of force. It is a fine balance, the tighter the fit, the better it works. Too much material, and it won't pull through.
It is amazing what comes out. Looks like nice sharp clean lead shavings.
I tried to simulate the Lewis system on the cheap.

Consider that for optimum results, cast bullets should leave the cylinder throats at least .001" - .0015" larger, then barrel groove diameter. Assuming barrel GD at .450" - .451", you can see that bullets from all but #4, are too small for "optimum" results.
Powder selection can "help" overcome this - to a point... Have you had the opportunity to slug the bore?
Another problem you may be experiencing, is bore constriction. Not a huge deal w/ jacketed, but will make your life miserable w/ cast. Constrictions of .001" - .003" are fairly common where the barrel threads into the frame, & also where the barrel is roll marked.
Constrictions can be located fairly easily, w/ a snug patch - in a clean (all lead removed), well lubricated bore.

Well, there is something to be said about S&W.
They are freaking awesome! I got the 625 back today. They only had it one week. Here is the report:
Condition- light primer strikes: replaced mainspring, replaced firing pin.
Condition- cylinder throats found to be undersized: replaced cylinder, recut forcing cone
Cost: $0
Now it is like new! Sweet

You did read my last post right? S&W found them to be undersized and replaced the cylinder.

Update.
Just shot 400 rounds out of the 625. Now, with a new cylinder. No leading and only took 20 mins to clean to like new. No dremel, no flitz. Awesome.

It's June now and I was wondering if you came to any conclusions on your leading/revolver problem.

Glad the new cylinder fixed your trouble. Just curious, do you know what size the new cylinder throats are? Have you tried dropping a jacketed .451" bullet in them? I had the cylinder on my 325 replaced (sticky extraction) by S&W & the new one's a little tighter (.452") than the old.

C17,
I have a 625-8, it is a JM, see attached pic. I traded a buddy for it and have fired nothing but my own reloads and homecast bullets in it. I have no idea what the other guy shot in it. But, it has been a very accurate gun with no leading problem. My load is 5.3 gr. of W-231, Win LP Primers and a semi-wad bullet cast from wheel weights with approx. 2% tin added. The bullets drop from an RCBS mold at 203 grains. I size them to .452" and lube them with home brewed lube, consisting of 50% lithium grease and 50% bee's wax, which results in a soft lube. It's one of my favorite shooters!

I should add that after mixing the lithium grease and the bee's wax I also added 6 ounces of liquid Alox. I ended up with about half a gallon of lube.

I havent measured them, but during my inital back and forth with S&W they said they were suppose to be .452. My old cylinder had some at .449.
The new cylinder looks different on the inside compared to the old. The new has a chamfered headspace where the old had a 90 degree break. They also supplied me with a chamfered cylinder ( loading ease) where the old one I had to have chamfered. Shoots a lot better. I have not tried a .451 jacketed bullet but I do have some good tools to measure with.
New Cylinder
I don't remember what my old cylinder looked like inside (& pictures of the defective chambers aren't clear enough to tell) but the new one does have honing (chamfering?) marks just forward of the headspacing ridge. Is this what you meant? My new cylinder had the chamber openings chamfered too, at no charge, even though it was an extra item I had requested & expected to pay for.

Been reading this all night. Dude you are stoked! I'm about to experiment with lead in my new 686P, I hope that i can make it work. All these stories about ECM barrels has scarred me!! Going to measure cylinder throats and barrel diameter tmrw and decide what size lead to start with. Good reading here and lots of great info, thanks.
A year old thread? Seriously?
