Does This Look Like Pitting?

If that is indeed lead fouling, Wipe Out also comes in a container marked Wipe Out Lead Out that works very well to get rid of lead fouling.

It's possible that if it is fouling, it may be from cupro-nickel jacketed bullets, such as those made by Norma.

That stuff can be a real chore to clean, if it's allowed to linger in the bore.

JB's won't touch it, when it's welded onto the groove/land surfaces.

The only commercial cleaner I've found that will remove it is SWEETS 7.62, which has a high ammonia content.

I have a personal mix that I make up for my own personal use, because I use Norma Oryx bullets for my 8mm hunting rifle.

I don't give it to anyone, the ammonia ratio is to high and if any of it gets onto skin, blued metal, stock finish, the results are painful in many ways.

Ed's Red will remove lead fouling if it's left in the bore and changed out every day for a week or so. Doesn't dissolve the lead, just creeps under it, very slowly, and loosens it up.

OP,
1st pic is carbon in the grooves.
2nd pic is erosion fwd of gas hole
3rd pic is copper or possibly corrosion that was layered under carbon from the previous owners neglect.

The lands look good,the grooves appear as if the button was dull when rifled.

250 & 400 grit silicon carbide lapping compound on a patch/jag will clean the bore better than new in less than 10 full pass/strokes followed by wet & a couple dry patches.

JB's will render you w/ tennis elbow before you get the bore clean.
 
Scope Pics - Follow-up to Post 23

Hey Gord - For my gas port I found some pipe cleaners on Amazon .ca. These are the 'old style ones with wire bristles as well as cotton(?) fibres. I'd scrub the port with a bit of C4 and then maybe bore paste, then a solvent like #9 and some oil. PS- they're good for cleaning the firing pin channel too! Goes all the way thru to remove crap that may cause pin sticking at the pin-hole. Last summer they were only $9.xx with Prime, now they're $18.22 !! Maybe a local Smoke shop carries them cheaper ??

NOTE - Here is a pic of my bore after the cleaning I described earlier. Used lots of patches but looks pretty good I think. You can see some pitting on the lands but it's mostly cleaned of fouling. Next pic is the gas port, the tube is slightly out of focus but you can see a bit of rust spots. Again, mostly clean too.

Thanks for the encouraging words everyone! I am glad this barrel is not ruined. I am going to take it to the range and fire several dozen rounds down the pipe and give it a good cleaning. Maybe this will blow out some of the crud?

Or do you think its not a good idea to fire this rifle in its current state?
 
I have read on this forum that firing a rifle will not "blow out the crud" - it will just "pound it" into the barrel walls. And have also read that firing a rifle can improve the bore condition - "wear off the rough spots". So, take your pick, I guess. You have a bore scope - that will allow you to see exactly what happened at the range - both before and after you clean it - might be a useful thing to post here - what it is that you find out...

I assume that you are in an urban area and getting to a range to shoot is a commotion - out here in boonies, I would take that one up the road a bit and fire off a couple rounds into the ditch and come back to my shop and take a look with bore scope - to see what that did or did not do.

Yes a range trip involves a two hour drive unfortunately.

Do you think the Bore Paste in the gas port could pose a problem?

I will certainly post after range pics tomorrow
 
Bore Paste in the gas port - I do not really know. Red neck / farmer / underground miner in me says the maker did not make it that way - and most military that use semi auto do not get paste like that in a barrel - I don't think - so I would think it is not a good thing - but what do I know - I do not own semi-auto gas operated rifles and have never been in a military. My gut says it doesn't belong there, but I have been known to be in error about what matters and what doesn't, many times before - just ask my missus (we've been married to each other since 1975) ...
 
Photo Update

Let's see some pics of your 70 year old SKS with f--- know how many rounds of bi-metal jacket thru it. :eek: Guess I should have noted which rifle it was. :rolleyes:
BTW - I'd think blowing the paste into the gas port would put into contact with the piston ?
Here's my 'new-ish' Rem 308 in SS with 3-4 rounds - a little better with just a dab of copper streaking. Just a patch with #9 then alcohol to clean. There are some chatter marks throughout the barrel, too. Just run-of-the-mill barrel, nothing special.
