Barrel Galling

Thanks for all the replies. The main question seems to be how I cleaned this barrel, well it is pretty simple. I clean usually 1-2 days after each range trip (10-20 rds per trip). I use Hoppes #9 and have been for several years. I soak a patch and run through the barrel followed by a saturated bronze brush for about 6-8 full strokes then dry patches until clean and final patch with light coat of Remoil. Same routine for years in all my guns.
The rest of the barrel is fantastic. It is just this one spot. Not slinging any blame on Krieger as this is an anomaly but I will do a thorough borescope now on any and all new barrels I buy from now on.
As a side note the Lyman borecam is fantastic! I'm sure a lot of us that have them will find things in their barrels that they never knew they had (some things we are better off not knowing). BTW this gun still shoots sub MOA even with the bad spot.
 
There was a bunch of barrels that had bad steel a few years ago. They opened up holes that looked just about like that. I can't remember what brands they all were. I believe a bunch of companies have since switched steel manufacturers. Matt
 
"raised up pitts...." Now there is a concept. Is that anything like reverse speed bumps?

Hey Eddie they call them POT HOLES!

I just received my Lyman borescope yesterday and immediately had to try it out. Boy was I surprised what I found in my Krieger barreled AR-10T! Has anyone seen anything like this before? It is about 3 in from the muzzle at 12 o'clock.[/QUOTE

Just had one I help with. Black powder gun looked the same . Had very little pitting but a large corrison build up . Good thing that Knight makes a tool for that problem . I thought it was was pitted but it was a corrison build up . Larry
 
Well now we know the type of cleaner an by not cleaning for two days it is possible if humity is right the Copper could be classified as a conductor an cause electrolysis I always wet my bores I don't think it is bad steel an a gun barrel will rust if what I said above took place.

Down here in Florida guns rust fast , going from Air conditioned homes to hot humid cars in plastic cases the guns sweat , and can have a lite coating of surface rust in the bore and on bare metal or whoever you touched in just a 20 mile car ride home from the range . Add a couple of days to that and the TIN WORMS show there ugly head .
 
try the iosso treatment I described It may lap out the pits and make it stop or slow fouling up at that spot.
Ive done this before and it works. I have a hammer forged barrel on a model 70 that looks like one gopher hole after another.
I Iosso it after shooting it , and it cleans out the crud and slicks up the barrel I
 
Thanks for all the replies. I have been doing some research and I think I will give this stuff a try:

Everyone one that used it seems to like it.

For those who read this that have a Lyman borecam, have you discovered any "surprises" in your barrels?
Be sure you purchase the KG Bore Polish also with it... I use the whole KG Industries system.. The polish will always come out black even after a good 24hr soaking with KG12, so I really recommend it for final clean up.. Don't over do the final polish though..

I am still having nightmares after viewing my buddies rem 700 in 7mag factory barrel. Boris Karloff stuff.
On the other hand, I viewed my new Douglas barrel and it was scene of perfection.

My smith said I had rust in my BAR 270 win chamber, and I babied that. I am wondering, while shooting at Yotes, in the cold, and being semi-auto, that the heat then cold naturally condensates in that area. Since then I had a coated cable made by Dewy that I put in a drill on one end, and a brush the size of my chamber in the other. I clean the chamber a lot more often now.
