shotgun questions (one has a lever)

[Larsen E. Whipsnade]

I have a "Coyote Cap Special Edition" 1887 shotgun that has an annoying habit of having the forend slide forward after just a few shots, even with low brass shells. I'm afraid to tighten the screws up much more for fear of cracking the wood. Has anyone else had this problem, and if so, how did you solve it? I'm hoping for something that doesn't require any permanent alteration to gun or wood. The only thing I could think of was to try putting some skateboard tape under the wood, but that seems a pretty Rube Goldberg approach, plus it might be too thick to avoid an unsightly gap. Any suggestions?

The other problem is a T.T.N. side hammer double barrel. At several places where the rib and barrels meet, it keeps growing a pale yellow substance. I've cleaned it off several times, but it keeps coming back. The longer I let it go, the thicker it seems to get. I've slathered it with Kroil, hoping it would penetrate to the source & kill whatever is causing it, but to no avail. I'm wondering if it could be some sort of residue from bluing salts. Anyone have any thoughts on how to get rid of it for good?

I'd like to know the answer to that also..................Mutt

You are correct it is from the bluing salts , the term for it is called bleeding normally occurs when the part hasn t been neutralized long enough after being placed in the bluing tank.
