Cannot get barrel totally clean

SNIP

2. If it's truly stubborn carbon fouling, get another mason jar. Fill it with SeaFoam (the stuff you use in engines). Drop the metal parts into the Seafoam and let it sit for a day. After the day is over, run a brush and patches down the bore.

Here's a pic of the bore (please excuse the lint and dust) after cleaning from the last time out (100 rounds of Federal aluminum case). As you can see the crust is still there but heavier than before. I tried Mpro-7 this time....no luck.

I've got the barrel soaking in Seafoam right now.....I'll see how it looks after a few hours.

Also, tomorrow I'm going to try and capture a bullet through some jugs of water.

If at first you don't succeed, try,try again.... Then stop, don't be a d*** fool about it.

A Lewis Lead remover will clean that in no time.

Okay, brushed the bore after it soaked for 2 hours.......some carbon and copper flakes came out but there is still a light crust there. So its soaking again, this time I'll leave it overnight and see if it comes clean in the morning.

The Seafoam should get the carbon out. If you have copper fouling, try some Hoppes Copper Solvent. Follow the directions on the bottle. Apply it to the bore, let it sit overnight. When you push patches through the bore, you'll get a blue/green color. Just remember, once you get everything out it will come back when you shoot it again.

Remember the old saying, "Perfection is the enemy of good enough".

At some point the the increasing efforts and money spent on various cleaning solutions will give you diminishing returns.

Thank you JaPes.

I just don't get why this is the only pistol of numerous I've owned over the last 30 years with this issue. I've never had a barrel that needed more than 10 passes of a brush with Hoppe's #9.

Is this common to SS barrels?

Once you get it clean I would suggest that you get some Klean Bore Lead Remover cloths and cut them into patches. Then patch your barrel for a half hour or so to remove the last traces of that fouling and Lap the barrel in a bit. Because these Lead Remover patches contain some very fine abrasives in addition to the solvents and by lapping that barrel in a bit you should reduce the tendency to foul in the future.

Good Stuff!

Wipe Out Brushless Foaming bore cleaner. Once I found this my gun cleaning chores became much easier. I was a bench rest shooter for many years. The result of this passion is that I am pretty anal when it comes to barrel cleanliness!

I keep J.B. bore paste and Montana extreme on hand but The above mentioned foam is the go to cleaner. I have a couple of barrels that it is easy to see the stuff work. It says to give it 12 to 24 hours to work and I have watched it slowly remove the copper. If used until all copper is removed future clean up will go pretty fast.

One more thing. If after it's squeaky clean you might look it over real well to see in the grooves are rough. J.B. will help with that! Good Luck.

Thank you Sirs.

My Model 19 showed some fowling from some hand loads I was using. I thought the barrel was ruined after everything I tried failed to clean it. Guys at the shop just pointed to RB17 and said. Just use a copper/bronze brush and this. Squirt it in and go to town as fast as you can for 30 seconds.
Looks like new again....

If the Seafoam doesn't work by morning, I'll order some of that stuff!!

 

[Bob O]

Seafoam didn't work.

Be sure to brush with vigor. Try using what you have and pretend it's your heart throb, give it good.

I use solid copper Chore Boy pot scrubbers. You can get them on AMZN if your grocery store doesn't have them. Some are only copper coated so be careful. Make sure they're solid copper. Snip off a bit and wrap around your bronze brush. Sparkly clean.

I bought a box on these at Walgreens last week. Next time I clean my gun I'm going to try it. The only problem is finding the pure copper ones. They seem to be hard to find since all the crack heads are buying them up.

Sweet's and Gozon work great....but if you do use an ammonia based cleaner, don't let it soak very long as ammonia plays havoc especially on stainless steel. I was a gunsmith for the USMC rifle team and we learned Sweets would eat rifling if left to soak. After all these years of different cleaners I have used, I found those bore snakes to work amazingly well for fouling removal. Good luck.

 

[Bob O]

I captured a bullet today, 6 jugs of water and then it hit the dirt backdrop and rolled down....so there are marks other than from the barrel.

I hope these pics are good enough. I have never examined rifling before, but it seems the grooves are a bit shallow?

Maybe this happened sometime earlier in the gun's life.

Barnes Cr-10. Use in a WELL ventilated area. If that stuff wont get it out nothing will. I had an original Rem 700 PSS that copper fouled like a beast and that stuff is the only thing that would get it clean. I also use it on my frosty bored surplus rifles.

Only other suggestion I have is to use a Lewis Lead Remover kit with some JB non embedding bore compound. If that fails, then call Sig Customer Service.
