Barrel Worn Out?

If I might, I'd like to direct the attention of some knowledgeable folks over to this thread:

I've photographed a segment of streaks in my barrel, trying to ID the nature of the beasty, and I'd appreciate more informed opinions.

Thanks.

Did you photograph the barrel before firing the gun? I don't know how SIG makes their barrels, but that looks like tool chatter. If so, it was there from day one.

8000 rounds is just getting started.

Take a good tight bore brush, wrap it with a patch that you kneaded full of JB bore paste. 100 strokes through the bore. Clean with solvent as you normally do. The bore will be smooth and the marks will be gone, it will also clean with a couple patches in less than a minute in the future.

I think that you have lead in the bore and that is what the marks are. Shooting FMJ lead is vaporized from the base and deposited in the barrel, it is also VERY hard to get out of a rough bore, much more so than typical leading from lead bullets. Unless you only shoot JHP or plated bullets I would bet that the marks you pointed out are lead.

No, it's not worn out. Looks like tool chatter to me too. If your pistol shoots ok, don't worry about it. I'd almost bet the 10 o'clock lint is from your patches and that there's another wee spot of roughness where it caught. The only thing that'll take it out is lapping the barrel. A patch wrapped on a cleaning brush, jeweller's rouge or lapping compound and lots of elbow grease. Run the patch back and forth in the barrel until the roughness is gone. Mind you, rule number one applies. If it works, don't fix it.

Thanks Gang!

I think it's time for me to quit being _quite_ so anal about scrubbing my barrells
