Wanted to Confirm WhatI am Seeing While Cleaning

[titanxt]

Hello All!

It is 12-degrees out, I am off for the day and bored out of my mind... I grabbed a rifle out of the safe that I haven't shot in a while and decided to make sure the barrel was clean and copper free so that I could mess around with some loads for it this spring. This particular rifle is my "Frankenstein" Remington 700 Varmint in 243. "Frankenstein" because I glass bedded the action, replaced the trigger, done some stock work, etc. on it to see how things affected the accuracy.

I ran a few patches of SC/Kroil 50/50 down the barrel and they came out the same color they went in. I then ran a brush (bronze) down the barrel a few times and when I wiped off the road I noticed it was as blue/green as it could be. I then ran a couple more patches of SC/Kroil down the barrel and they were as blue/green as the statue of liberty... I then dry patched until the bore was dry and used some K12 copper remover as per the directions.

I left the K12 in the bore overnight and when I woke up this morning, I dry patched it out. It came out as lime-yellow as it went in - no orange color at all. Wondering if I was not seeing thing correctly, I used a nylon brush with some SC/Kroil and brushed the barrel again. No blue/green color at all. I then used a bronze brush again and too a few passes and the blue/green color returned in full force.

Is the color I am seeing coming from the brush and not copper in the barrel???

Thank you!!!!

More than likely, yes. Bronze brushes are notorious for giving false positive results when testing for copper fouling.

Yes, a bronze brush will always leave copper/bronze in the barrel - if you "chase" it, you will never stop cleaning your gun.

get this cheapo borescope. It isn't the greatest, but it will help identify if you have coppering in the barrel.

It's out of stock, but when it is in stock I would get one. Can't be 20 bucks, which is what I paid for mine.

In Stock and have to try this $20 bore scope. It's worth it just to tell my $500 bore scope friends.

It is not the greatest, but what do you expect from a $20 dollar endoscope.

It doesn't show in detail, the grooves in a profile view like the $500 dollar ones and firecracking, but it will show you where you have copper, fouling, etc. In a clean barrel, you can actually make out some stuff like firecracking or the start of it or bore wear.
