Title: marks on cylinder face
Post by: LonesomePigeon on November 23, 2016, 10:22:33 AM
Here is a link to a gunbroker USFA that I was watching. Picture number 7 shows some marks on the cylinder face. Can someone tell me what these marks are, if they're just normal marks from being fired?

I would say not from being fired.  BTW, this gun looks like a few that USFA had color cased by Classic Guns out in IL.  Their colors had more gold than Turnbulls.

I saw this same gun listing. It looked to me like leading, but I could be wrong. I had very similar marks on my cylinder from using Ultramax ammo (I don't get it from Black Hills ammo, which I use now).

I was able to remove it - it really did look like scratches at first, and I read through several forum posts to discover that it was just lead residue. I saw several folks note that wasn't a big deal, and to be cautious how you remove it from a blued gun (you don't want to use lead-away clothes for fear of damaging bluing, from what I read).

I don't know if this is the case with this revolver, but to my naked eye and the photos it does look quite a bit like the lead I had on my cylinder after using that Ultramax ammo.

Leading.

That's what those bright spots are - minute (some not so minute) flakes of lead peeled off at the forcing cone.

Thanks for the replies. I take it leading could happen to any gun if you are using ammo it doesn't like?

Not really.

It 'can' happen on any revolver when the cylinder isn't properly aligned with a properly-beveled forcing cone, or if the cylinder's out of true.

Piling ON here.  I'm with St. George.  It's lead.  Not a lot of lead, but lead.  Were It my gun I'd be putting a range rod down the barrel to check cylinder/barrel alignment and taking a hard look at the forcing cone.  Actually I'd have done all that before I fired it and would have re-cut the OEM forcing cone to 11 degrees.  Nothing magical about 11 degrees.  11 degrees just seems to work quite well.
