ok

just got an old milsurp bolt action ....303........seems used but not overly abused.

ok........previous owner told me he shot pretty much only cast bullets and a few factory loads thru it .......in the last few years .....

sinces its ww1 era............lots of hands have passed over it ......many shots down range .....

QUESTION ........
currently am trying to clean the bore best as possible ..........am scrubbing it with copper brush ands hops solvent ................then patch it thru and swab it with sweets .7.62 thru it .............following thier directions of course .

been at it a week bout an hour each evening still getting either black patches or blue/green from the use of sweets .

how long much more work to be clean ? ANY alternatives /ideas?
i had a similar problem with a nagant just gave up was all and well, .......just asking .

thanks all.

Never tried Sweets. I tried Hoppes Elite Copper Terminator the first time I ran into a coppering problem, but a friend then recommended Barnes CR-10 to me and it worked very well. It's my standard now.

Have you tried a steel brush? (Bronze is of course largely copper and a bronze brush will react to the decoppering agent.) I found that helped me when it got really cruddy.

I've known old firearms in particular to 'leak' virtually forever. I guess the $64 question is how well does it shoot? If it shoots well and if it's not corroding, then I wouldn't worry overly. If it's just a collector piece, cancel the shooting part.

Good luck.
 
I would try using a 30 calibre jag and a 30 cal patch loaded up with JP BorePaste. It is a thick clay like abrasive paste that works wonders on old crudded up bores.
 
"Sweets"

Been using "Sweets" for years it's great stuff! You probably have a lot of copper plating the bore over the years . Maybe leave it a little longer in the bore. ---- ( NOT over night !!) Also a few more scrubs with a bronze brush ?
Owned a few where I really had to work at it after years of some soldiers neglect.

Just reread your post --- if the guy shot a lot of cast bullets no amount of Sweets will clean it .
Try an old worn out brush wrapped with some strands fr. a scouring pad which is 100% copper (won't hurt the bore) Run it thru dry no solvent whatsoever ,as needed , it will rid the bore of most if not all of the "leading" .

J-B Bore Cleaner

J-B Bore Cleaner gets caked-in powder residue and copper jacket fouling out of barrels. This paste is non-embedding, which means it doesn't get stuck in the pores of the barrel.

J-B Bore Brite

J-B Bore Brite is a micro-fine paste compound that works as both a cleaner and a final polish. Regular use gives your barrel a mirror-like finish that helps prevent build-up of copper and carbon fouling. J-B Bore Brite liquifies during use to quickly remove fouling and powder residue in rifle and handguns, and plastic deposits in shotgun bores. Regular use between strings minimizes accumulation of fouling to help maintain accuracy.

Shot over 3,000 rounds of lead 22LR down my 597 and never cleaned it. It looked like a shotgun barrel. Then I used this and WOW!
Due this 1, 2 combination then clean normaly. Then put on some shade's cuz it is going to be bright & shinny!
 
Your on the right track, HOWEVER

Your on the right track with cleaning your bore. Do not use a bronze or copper bore brush or jag if you are using cleaning compounds that remove copper, You will continue to get an indicated color change because you are dissolving the copper, bronze material from your brush, jag. When you have a build up of lead and copper in a bore that probably has never ever been properly cleaned with the proper compounds it can seemly take forever to remove it all. Then too most of the compounds out on the market are just snake oil and do nothing but make you feel good about cleaning your weapon. There are only a few good products on the market that do what they advertise. One of them is WipeOut. WipeOut removes copper really well but again it takes time and it may take as many as 6 or 7 applications or more over night to get rid of all the copper. WipeOut does not remove lead, it does however remove and break down some of the alloys that lead has in it and then the lead comes free from your bore. I use a combo of Sweets Bench Rest and WipeOut in my 50 caliber Kentucky long rifle flint lock to get the lead out of the bore when I am shooting Mini balls and maxi balls. I use plane old WipeOut in my smokless powder rifles that use only copper jacketed bullets. Hope this helps.

I use COPPER pot scrubber wrapped around a .22 caliber bore brush to get out stubborn lead in a barrel. Cut a strip with the scissors & wind it tightly on the brush & use it dry at 1'st, & then later with some bore cleaner. The copper will remove the lead quickly without harming the bore.
Then clean with your barrel like you normaly would.

Make sure it is the copper scrubber & not the copper plated steel type! Always test with a magnet..... :)
 
bought and tried wipe out ............after 5 overnite applications , a bit of scrubbing and a little carb cleaner...........barrel is clean.

1 down 4 other old milsurps to go.
 
Eds red works wonders. Doesnt do anything for copper fouling but destroys any nastiness in your barrel.

I dont think copper is your problem anyhow.

My lee was dirty as well, but scrubbed with eds red and a bronze brush, and it cleaned up great.

Another tip is to shoot the rifle and clean right after shooting while the barrel is still warm. You can dislodge a lot more stuff that way.

After doing that with eds red my bore was ###y. Not quite shiny bright, but shoots real tight groups. So why mess any more with a good thing?
