I have a pre nickel-steel barrel on my old Winchester that is in need of a good cleaning. No matter how many times I pull a patch through it, they come out with black on them. Powder fowling, or lead?
Will using JB compound bore cleaner damage this old barrel in any way? KD
 
JB will not damage the bore.

If you mean that you are already using the JB and the patches are coming out black, that will not change because the JB fouls the patches with microscopic particles of metal as it polishes the bore.

Just run a few oiled patches through the bore and you will see the difference. ;)

Try JB on a new brush rather than a patch, you can wet it a bit with Hoppes #9 as well. Scrub it about 50 passes adding more JB along the way....and then patch it a few times... you won't get it any cleaner with any more scrubbing. Only a soaking with a chemical copper cleaner would do any more....

and JB will not harm a bore....
 
Quit using multiple patches. Swab in some solvent and leave it there for half an hour or so, then run a few patches through and repeat if required. You need to give the solvent time to work.
 
Get yourself a cork and plug the barrel at one end and fill the barrel with 1/2 vinager and 1/2 hydrogen peroxide and stand it up against a wall so that it won't fall over. Let it sit for about an hour and then pull the cork over a sink to let it drain. Rig up a hose with a copper end or have a small funnel that will fit into the breach end of the barrel and pour hot water down the barrel for about a minute. Now run a cotton swab thru it and in about 3 or 4 passes your barrel will be completely clean and shinny, all crap will be gone lead/copper what ever. Caution: the vinager/peroxide solution will take off blueing on contact so be very careful not to spill any.

Did this to a 1886 Win. a couple of years ago, plugged the muzzle, i put in a small flexable funnel in the breach end and filled it up. Let it sit for 1 hour and drained and flushed it out. Put the rod thru the barrel and attached the patch at the breach end and pulled it out. Did this 5 times until the patch was clean and holy crap the inside of the barrel was blinding when I put a bore light down it.
 
I wouldn't pour vinegar down any barrel it will corrode the barrel. I would use hosehold ammonia. It is corrosive to copper/brass but not steel. Plug barrel and soak with amonia it will remove any copper fouling. To test for copper fouling, wet a patch with ammonia run it down the bore, let set 5 minutes and run a clean patch through . If the new patch comes out with blue or green streaks you have copper fouling. Ammonia is what is in most of the factory copper removing compounds. Its just a lot cheaper buying house hold ammonia from the cleaning section of the grocery store.
 
i used sweets 7.62 to remove copper . take a brush give barrel 10 or 20 full passes. using regular gun oil /solvent like hoppes.
put on a jag, wet a patch with sweets, run it thru bore, wait 10- 20 minutes. then use dry patch then check bore, repeat till patches have no blue greenn residue on them. can take a lot of work.
did a no 5 jungle, a smle , a nagant, my m1 garand, a 7.62/k98 isreali.
worst fouled was nagant an the 303 jungle.
may try the other methods on my new fixed up/ld 6.5mm krag. but my other barrels are rather clean now.
 
I use the new RED JB bore bright to start with and I put it on a tight fitting patch. Best is the wrap a patch around a slightly smaller brush, load with the the JB and fly at it.

After 25 to 50 strokes (you will feel things smooth up), I clean it all out then switch to reg JB. Clean that all out and you should have as clean a bore as you will ever get.

Now if you still see chucks in the lands/grooves, odds are that is lead. Get some lead out cloth (I think kleen bore makes the stuff - yellow material). Cut a moderately tight fitting patch and swab away. In a few minutes the patch will be black and the lead will be gone.

Now you can see what you have for a bore. With jacketed bullets, pitting and such will not be too bad for accuracy. For cast bullet, not so good.
