Is this normal?

That looks like results of heat and whatever handsweat, cleaner, or some other chemical that was left on the bbl. Anyhow, it does not look at all serious.
 
I also do not think the barrel is harmed but it does look like a trace of something left behind for either water or think cleaning substance.... your right on 10-96.
 
Thanks for the replies, seeing that the barrel is a pretty important part of a firearm (lol) i just wanted others opinions on the matter. I own many guns but have never had that happen before so i was just curious, thanks again

It's all really subjective and relative to your point of view. If you were to remove the barrels from your firearms, think of all the money for ammo you'll save. You'll also save wear and tear on all the other parts as well, and well- the barrels themselves will likely never wear out. Of course the fallbacks are you'll experience much less fun and personal enjoyment, may develop fits, and possible bouts of severe constipation if one does not shoot on a regular basis.:D
 
If you are worried about potential cracks, just get a can of spray penetrant to check. (Any good aircraft mechanic can tell you where to get it.)

It's not inconceivable that you have hairline crack forming from crystallization of the metal.
 
Barring some really weird manufacturing defect,when a cylinder (i.e., a rifle barrel) fails
from pressure, it splits lengthwise. (think hotdog) ;)

I wager the white bands are the effect of high heat on areas where cooling oil from barrel
shaping/lathe work was not "completely" removed before Parkerizing.

The barrel is fine. You are seeing the remains of fluids the have heat evaporated off the barrel surface. They well disappear when you oil the parkerized surface. You well see similar marking the next time you get the barrel that hot.

I treat parkerized metal with Eezox, it leaves a non-oily feel with a nice even color. Best protection available.

This could very well be also. If you see the same marking appear the next time you get the barrel hot it is probably a defect in the Parker Rust Proofing.
