Leading in my smooth bore

[varsity07840]

I need some help with what I assume is a leading problem with my 20 ga Kibler. I used over 50 patches, a brass brush and Kroil and still get black patches. I feel what I think is a crud ring about ten inches ahead of the breech. Can this be caused by badly blown patches? My .600 ball/.010 patch loads very loose and really blows up the patches. Again, I assume the black is lead. I’m going to attack it again with chore boy strands on the brush with the rod chucked in a drill.

Try Windex with ammonia.

Hard to say but I use a .605 ball with 0.015” patch in my .620 Ed Rayl barrel. I know the math doesn’t add up but it does load. Any loose load fouls badly for me and the patched ball does not clean the fouling from the previous shot. If shooting frequently, at range or woods walk I use a pretty tight very wet patch.

 That really sounds like a lube problem, rather than a lead problem. Some lubes polymerize with heat, and create a crust in the barrel that is hard to get rid of.

Try a Tornado brush.

Well, I use mink oil exclusively. I guess my main concern is that it’s not rust, although how that would happen is beyond me. I’ve been shooting MLs for nearly 50 years and never had this problem. I have however, seen leading in BPCRs which is why I thought it was the problem now.

I really like the "Big 45 Frontier Metal Cleaner" pads.  They can leave light scratches on a high polish, but are great for cleaning a bore.

Black could well be graphite.  Mr Flintlock or original Lehigh Valley Lube will remove Graphite.  Give it a try.

Leading should come out as flakes on a patch.

Or steaks of silver, never black.

Graphite? Rust? It’s a new barrel-cutting oil residue?

I think smoothbores tend to be harder to get perfectly clean, I’m not sure why. Maybe it’s a function of the larger bore or more residue from lower pressures or I don’t know what. Shooting shot adds to that of course. I have started using hemp tow and a worm. It seems to speed things up some.

Don't know how you are cleaning, but it takes me half the time to clean a smooth-bore barrel than it does to clean a rifle barrel.
