inside of shotgun barrel

[G38xOC]

I have shot roughly about 80rds of slugs through , noticed some glue residues right around 1-2inch pass chamber area . it doesnt look like carbon build up . color is clear , not black . I tried few methods using carbon removal , ballistol , inside of barrel i got to clean real good other than that part of glue looking residues and just wont **&^% come off !!

is that part of wad or somesort of plastic melting off inside of barrel before flying off ?

Sounds like wad build up. Not a big deal. More common as many new guns are not as well machined and polished as they were decades ago.

There are hones to polish the barrel. Once clean, inspect the barrel. If rough, there are cheaper and more expensive methods to polish out the rough areas.


As simple as wet sand sand paper and a wooden dowel with a slot cut into it to hold the paper and cutting oil.

I have...residues right around 1-2inch pass chamber area...is that part of wad or some sort of plastic melting off inside of barrel...

I presume that you are talking about the new CZ that you got recently.

That area that's fouling (close to the chamber) is called the forcing cone.
I don't ever recall seeing/hearing about a plastic build up there.
Usually, if there's plastic fouling, I've noticed it in the choke (tube).

Other than some folks that have said they had to hone the chamber of an 870 barrel, I don't know anyone that uses a hone in their shotgun barrel.

Many shotgun barrels are chrome lined (don't know about CZs).
I personally wouldn't use a hone or sandpaper to clean the bore of a shotgun, especially on a new firearm.

Try using a patch and hoppes #9 to clean it out.
If that doesn't work, you can:
Call CZ and see what they recommend doing.
Or wrap 0000 steel wool (with hoppes if you want) around a bore brush attached to a cleaning rod and use a cordless drill to clean it out.

Learning something new everyday . Ill those method a try ! Thanks

I was going to try that wad solvent first without honing first . I see it on my 870 as well pretty heavy build up. Don't think last owner kept up with cleaning much .

Honing to a fine polish is common in cowboy action to try to make the chamber area as slick as possible. That said, it has nothing to due with general cleaning or wad build up.

I'd use a wad cleaner and a brush.

OK, What you are seeing is plastic transferred from the wad as it goes down the barrel. This is common and happens to all levels of guns.

Rule #1 is that if you have Chrome Lined Barrels do not use any kind of abrasive to clean it out. That plastic wad solvent will do it just fine and not hurt the Chrome Lining which is supposed to keep plastic transfer to a minimum in the first place...

I am heading to the shop right now to use a Flex Hone on my new barrel that just got the forcing cone lengthened. It came out a little rough for my tastes and I can easily fix it.

The thing I use to clean my shotgun barrels most often is a "Bore Snake". I pull it thru the barrels after every shoot. I usually only fire 50-100 rounds at any given shoot so the plastic transfer is minimal and doesn't build up and the Wire Bristles on the Snake remove it in one or at most two strokes..

I have had problems getting plastic transfer out of the ports on some of my barrels. That is a PITB and I try to avoid it as much as possible. The Choke Tube Solvent cured that problem but it wasn't that easy to get all the little holes clean. The ports tend to act like a Cheese Grater and cut the wads producing little slivers of plastic which are hard to get rid of. But not impossible.

PS the site is now running pretty well. Good Job guys!

I'm not sure Remy 870 barrel is chrome lined barrel .

[hermosabeach]

Correct
hone is to correct rough machining in non chrome lined bores

if the forcing cone is rough, it can trap plastic from the wad.


to keep cost down, manufacturers change the process.
forged parts and machines parts are now MIM- metal powder meted and formed into a solid.

surfaced that were polished and blued are now coated to hide scratches

bores that were polished like glass can be rough


WM
do you have a bore scope where you can film before polishing and after?



I also have a forcing cone reamer to clean up non chrome lined barrels and slightly smooth and lengthen the forcing cone.

[JagerDog]

Ed's red with the acetone for plastic build up. Just keep it off any plastic parts or stock finishes.

I honed my new barrel after it came back from Vang Comp, The forcing cone was a little rougher than I like, so I went after it with my Flex Hones. Bummer was that my 400 grit hone is pretty much wore out so I had to do most of the work with the 800 grit Hone. The bore is like a mirror now !

I don't have a bore scope so I can't really show it but suffice to say it looks like it is Chrome Plated now. But it's not..
