Leading

I have been getting some leading on my s&w 617 in a few spots on the frame. On the top strap, at about 5:00 oclock below the barrel, and on the extractor rod collar. Is this normal, or is the timing most likely off ?
thanks,
Haka

Not with a revolver you get powder flash from the cylinder gap. Leading can be caused from several things with bullet fit to throat the most critical. The use of a hot burning powder like TG will cause leading in anything. 2400 is my favorite powder when it comes to LSWC in my 357mag.
What are your loads your shooting?

Thanks for your reply Blue, the 617 is a 22lr, but great info just the same. Fed Blazer bulk.

Fed 22 ammo normally does not lead. Are you sure it's lead and not powder residue? There is not a lot you can due except try a different ammo. With Fed you need to look at the load numbers. They use the same load on about 6+ different labels.

Now that I think about it, I have shot some Rem Goldens thru it. Quite sure it's lead, have to scrape it off and it appears silverish.

May want to have it checked. But Rem can cause leading.

How did you ID the residues as lead?

Consistency, color, and difficulty removing were my indicators. I basically had to scrape it off. Although I went out again and shot some Rem G's and it didn't have any leading? If I get it again, I will be very careful to identify. I can't say for sure, but it sure did look like lead.

I've gotten lots of black gunk that needed scraping around barrel and topstrap. I also pulled some lead in the same place. The lead cut off and looked shiny.

What's your best method of cleaning lead in those places?

I used a pocket knife to scrape, followed by a bronze brush and solvent. I'm sure that's low tech and not the best way to do it but the knife will cut most of the lead and crud away, leaving a dirty top strap and barrel.

When it comes to thick leading, I have a blade from a retractable utility knife I use. It's long blade surface helps me get a lot of "even" pressure to prevent scratching the surface. The best way to remove lead, although, is to not get it in the first place.
