Bore turned green?

[fordfan485]

Anyways i read in a book that if you arnt going to clean your rifle right away to soak the bore in hoppes put a patch on the bolt close it and then rubber band a bag at the end and hang it upside down so that it would drip out of the muzzle and not into the chamber. Anyways 3 weeks later i go to check on the rifle and at the muzzle there is this green ring of goo around the muzzle and in the bag, should i be concerned.

Green could be copper residue ? Just guessing.

What book told you to store a rifle with solvent in the barrel? Yes the green is copper. However you should store it with oil in the barrel not solvent.

green is copper fouling. In general you want to store a gun with a light coat of preservative oil in the barrel., not solvent.

Now there is Hoppe's oil, and that would be good.

This is actually the application I like Breakfree CLP for. I think its a lousy solvent/lube, but the "protect" aspect is pretty good.

What he said.

Also, you could use an ammonia-based copper solvent to get the fouling out. And don't store the gun with solvent in it. You can leave it in for 15-20 min or so to soak, but beyond that I see no reason.

Instead of Hoppe's I'd use something more rust-preventive like RemOil.
