Copper removal

I have this barrel that is not coming clean. So this is what I have done so far.

I like the foaming bore cleaners. I have the older Gunslick in the large can. Normally it will clean any amount of copper in 2 sessions. What I do is fill the whole barrel and chamber up and let it sit over night. I have done this 5 times already using Amsoil bore cleaner to wipe out any left over.

I then have used Sweets 7.62 in the bore 3 times. Leaving it to sit about 15 min each time.

I do not know where to go from here. I guess I could do more soakings from the foam bore cleaner????

What do you think?

Never worried about removing copper out of my barrels. All my firearms have been as least initially test fired with factory ammo or jacketed bullets, I reloaded..............in the hundreds before switching to cast. However, the rifles and carbines were almost always cleaned with Shooter Choice or Butch's Bore Solvent after each use of jacketed. My targets never suffered.

What is the approx round count in that barrel? Sometimes that impacts my decisions on what to do next. Meaning, call it good enough or keep going with new techniques. Also, I agree with others, a bore scope sometimes can cause me to think something is a problem when it is not a big deal. I own two bore scopes and I have learned to stop myself from using it more often than not. However, there are times that I would not be without one.

Looks like some serious erosion at the throat. I assume that hole is a gas port and this is a semi-auto. I see erosion at the muzzle end of that gas port, too.

Agree with Dimner, nasty gouge at crown.

I'm chuckling as I type this. I have a borescope and I checked the barrel on my 03 when I was struggling to get it to shoot. The bore was less than perfect. Lots of pits, all of them shiny, but still lots of pits. I was getting ready to replace the barrel with a Criterion or similar when I tried some oversized cast bullets and the rifle turned into a tack driver. I get compliments on the groups I can shoot with that rifle and my standard reply is "Thanks, not bad for an old pitted barrel, huh?".

Pits!? Pits, you say? One of my perverted friends weaseled me into allowing him to penetrate a perfectly splendid shooting 4 groove 03 with his perverted bore scope. You've all seen mud puddles that have dried up and cracked right? I think I have mentioned this before on this forum. The area ahead of the chamber of my fine old Sporter looks like a dried mud hole. I caused me PTSD for awhile. All it takes to reignite the trauma is the words, "Bore Scope."

The crown is fine. That is some oil an lint from pulling the patch back through.

The barrel is melonite coated SS.

There is approximately150 rounds on the barrel. I did an initial cleaning at 5rds then 15rds. Then shot till where it is at now.

Not sure if this applies to barrels intended for jacketed ammo, but Dave Hicks, US BPCR team member and record holder for 1500 yds if I am not mistaken used to shoot with us at Wilton. Dave said a new barrel needs 100 rounds put thru it with a patch run down the barrel between every shot. I did this using a smokeless load (Unique) at the club one day. Takes forever but I have to say that when I shot in matches, the Shiloh did its job if I did mine.

I don't think that's copper, Tom. You get some weird, splotchy brown oxides on SS from shooting sometimes. If it was blacked on the outside, it may have had a light coat on the inside and it's coming off here and there. JB it if a patch is draggy, otherwise just shoot it. The nasty burr from drilling the gas port is typical and will wear away and become a pit later.

I really like TM Solution. Removes carbon well and copper too. Very easy on steel so I apply a bunch with a wet brush and leave it overnight. A few wet patches in the AM and the bore is much cleaner.
