Rusty Bore

[Alberta Black]

Hi folks

I have acquired an old CVA Mountain rifle that was neglected and the bore is rusty. Any thoughts on the best way to remove the rust from the bore?

thanks

How rusty is it ?

Get a slightly under bore sized jag and some purlap patches to start. Damp and wipe. Then use a regular patch to "feel" how smooth you got it. If still rough, try with more burlap and some polishing compound such as flitz... If not smooth yet, use some 0000 steel wool and then feel again. If not, try some of the auto scuff pads. If not, it is toast -- rebore, have it wallowed to a smoothbore or get a replacement.

Scrub the bore with JB Boreshine followed by JB Borebrite. The second step is nice, not necessary; you will probably be pleased with the result with Boreshine only; you will get a mirror finish.

This will polish the bore and remove every bit of fouling, but once the bore is clean stop, because a patch with this polish will still come out black, probably forever, even in chrome lined bores.

I flush the polishing compund with Hoppe's No. 9 on patches.

Thanks for the suggestions.

I have taken out the first layer of rust and yes there is still sharp rifling under there. I suspect this is a case of neglect by an individual who had little knowledge and patience with traditional guns.

Hi there you may want to soak with some wd40 or Kroil or what ever penetrating oil you have to help loosen some of the rust I like Kroil myself. Try to follow the steps listed my the gents above the JB bore paste is good stuff. Good luck and let us know how you make out. :m2c:

I just caught that "First layer" part you stated. If you have layers it is etched & pitted. You may get the rust out but you will never get the pitting/etching out. Now that doesn't mean it will not shoot or you can't have a good time with it. It means it will not perform to what was at one time possible, but still can possibly perform remarkably & quite possibly better than most can hold it !

It will be necessary to clean it quite well with a brush if the bore is etched after every shooting, as the deposits can get trapped in the etchings /pits & thus cause more rusting & be where a cleaning swab cannot reach. I would get out all the rust I could, then go shoot the heck out of it & have some fun.

:thumbsup:

Surface rust comes off easily with some elbow grease. Then again, I'd shoot it out with a patched round ball. Why work so hard?

Aero,
Where does one get Bore Shine? Thanks for the help.

Well equipped gunshops carry JB bore paste, and of course Brownell's has it, but you can find numerous internet suppliers if you search in Google. I would ask a local store to stock it if I were you.

The important feature of this product for shooters is that it won't imbed abrasive in the barrel.

Target shooters in particular use JB to clean the copper and last remnants of powder fouling out of rifle bores, but I used it in a .303 British rifle I had leaning in the closet when I noticed the bore was rusty and I was amazed (I knocked down the easy rust with solvent and patches before I started the JB paste) at the polish.

I also used this on a new TC Hawken kit barrel I bought at gunshop that was going out of business - I don't know if it helped the accuracy (that's another story), but I got the blueing out of the bore.

[Note: it's not the same as Butch's Bore Shine, which is a liquid bore cleaner; I use both and got the name wrong in my first post.]

Alberta Black I had barrel like your talking about i took a scothbrite pad the green one cut it 3/8 long strip wraped it around the ram rod with tape on each end and run up and down the barrel.It removed rust plus took of the sharp edges of the lands and polished it real good

AeroE,
Thanks for sharing the info on the JB Bore Paste. I'll give it a try on a pretty badly rusted T/C renegdae barrel I just picked up. I usually lap such barrels with valve grinding compound, but will give this a try.

I like this notion, too - it's certainly better than doing nothing and shouldn't cause any more damage. I would include some oil to help break up the rust and frequent clean patches at the start to get the worst of the rust out of the bore quickly, then work on polishing the clean bore with the scotchbrite.

I finally got all of the rust out with a combination of JB's,WD40. some eblow grease and lots of patches. There is some pitting but I think that the gun will still be accurate enough for my needs. Now off to the range next week to see how it works.

Once again thanks for the input.

Next time try naval jelly and 0000 steel wool.

I have a takedown Winchester 1894 made in 1924 that has the worst bore you ever saw for about 3 inches in front of the chamber, but the rest of the bore is very good; the gun shoots like a house afire, I can easily get 6 inch groups at 200 yards off bags using the stock iron sights. (That would be house afire for this class of gun!)
