Leading??

[Tabby Lynn]

Did you use exactly the same batch of ammo in both revolvers?
Did you use this ammo in M15-2 before with no problems?
Also in the picture it looks like just naked lead and not coating.

I agree with Sgt Rock, lead on the face and edges of the cylinder is pretty much normal. You may be getting a bit more on one revolver than another because of cylinder timing, but much more likely because of the flat wad cutters you are using. Try using Acme coated wad cutters or preferably semi wad cutters. (www.acmebullet.com) They are extremely accurate, inexpensive and their coating cuts lead fouling to negligible.

Man ... I didn't think anyone did that anymore.
it's mostly hitek or powder coating lately, where the only pitfall seems to be cut corners in the oven cure time.
For a time in the late 90's into the early 2K, moly was all the rage till folks discovered rust pitted bores from the stuff. Otherwise, the stuff worked.
It goes along with my vapor phase deposit theory. it doesn't protect the base of the bullet like plating or current poly coatings. Nor does it dilute the vapor deposit in sludge like traditional lubes did.
I'd say the stuff is doing it's job, despite the pitfalls of the system

I thought Moly was long dead and buried but I guess not? As far as the front of the cylinder (for the OP) they all get dirty. Just clean it off. There will be some left but no need to go crazy cleaning as it will just come back next time you shoot.
