blueing mottled?
I have a T/C Omega w/ blued barrel, shot it about 2 weekends ago cleaned it well and put it in my gun safe. When I took it out tonite I noticed the blueing was mottled on the top of the barrel about 6" back from the muzzle (looks as if the blue faded and you can see light and dark patches). Has anybody had or heard of blueing problems with T/C or any ideas of what may have caused this.
