After removing and washing them, they still had a nice ring to them but I wanted to determine the integrity of the solder joint so, using a hammer and centerpunch, I attempted to break the joint. After delivering 4 blows with the hammer, with the punch directed at the point where the tubes touch, the last 1 1/2" inch of the joint separated when the ribs deformed but the rest of the joint remained intact.
I wanted to see the insides of the tubes so I cut them in half on the bandsaw from the breach to the muzzle.
The electrolysis appeared to have done a very thorough job on the pitting in the bores but as you would anticipate,the rust in the void was still present.
If anyone has any experiences regarding this I would like to hear what you concluded and if anyone has any interest I can send you a picture.
