UPDATED INFO>>>>

OK... I just ran a brush thru it with Hoppe's on it. I scrubbed it 10 times each of 3 times using a bronze brush. It had no impact on it. Nothing... notta.... zip. the hazy marks are as they were before scrubbing.

Next -

I used the brush again with a little Sweet's on it. The Sweet's was starting to disolve the brush evident by the bluish color in it but again, no change on the white haze. The longer I look at it, the more confusing it gets. Something tells me it's heat related but why is it at the muzzle end....?

I can't see down the barrel to find out what it looks like near the chamber or throat. I'm at a loss here.

I suppose I'll try shooting it once more before I condemn it.
