JB bore paste
 

How do you guys use it when kinda polishing a new barrel? I have always added some oil to it and use a patch on a snug fitting ramrod and work it up and down a bunch of times. I overheard a fellow talk about using it on a bore brush. Just wondering

Both ways will work... I use a tught fitting patch.

I dont use it for polishing it is for lapping and to do that right you use a lead slug either poured in that barrel or swedged in it, other wise you round the sharp edges of the rifling not good for accuracy.
If you just want to polish it a little use jewlers rouge you can pick it up at a hardware store where they sell polishing wheels and such. Lee

Where do you guys get your JBs from?

RE: JB bore paste
 

MidSouth Shooters Supply, but a lot of Wal Marts also carry it.

RE: JB bore paste
 

Brownells carries it also.

Sportsman's Warehouse is where I get mine.

I don't mean to start a big debate but you seem to be the only one that feels that JB bore paste is too abrasive to use for polishing. I know a few benchrest shooters that use it fairly regularly and I used it on my new stainless Omega that I could not load any sabots without extreme pressure. It did not seem to affect accuracy with 200 passes of JB on a patch over a well worn brass brush. Loading did become easier and that was before the easy load and crush rib sabots were available.

MLKeith, Yes thats all true, and if you have burrs on a cut barrel like the TC's its good for taking them out fast.
However like you said people that work with that sort of thing form opinions, mine is that for the high polish that makes muzzleloader load slick and clean easy regular polishing compound is better. Lee

Lemoyne,
I really don't know much about using JB. I just ordered it. According to what I've read (of course, according to the manufacturer) they claim it is finer than jewlers rouge. I certainly don't want to cause any damage. You feel that it's not true?

"If you just want to polish it a little use jewlers rouge you can pick it up at a hardware store where they sell polishing wheels and such. Lee"

Bingo, Lee. Get mine at Hobby Lobby. Savage centerfire barrels are usually very accurate but are often very rough: I use jeweler's rouge on a patch to get the roughness out. Also smoothed out several Encore barrels, including my own with it.

We used to shoot benchrest and JB was one of the items everyones shooting box had. When mixed with oil it can be made in any texture you want. I suppose any polishing compound would work but for me JB is what I will use.

RE: JB bore paste
 

Old/New, a lot depends on what you wish to accomplish, from reading your first post I got the impression that you did not have a problem and just wanted to a better polish than the new barrel comes with. If you have burrs or tool marks to contend with then I would start with JB and clean it up,now thats as far as most go, I personally load very tight and try for extreme accuracy so I want a mirror finish. I have no arguement with anybody on this because in the end it boils down to what a person wants to end up with. I do feel if you need to remove some metal as in tool marks or burrs JB is best, I also feel that where it leaves off is where the jewlers rouge starts.

try 0000steel wool raped on a old brush with JB .

RE: JB bore paste
 

Thanks...I think I've got a use for it then!

RE: JB bore paste
 

As mentioned I believe jewelers rouge comes in multiple grits so I would be careful just buying something over the counter at a hardware store unless you and the sales people really know what you are buying. I will still stick with the JB when needed as I did not feel that it was very aggressive. My Omega barrel was pretty rough and being stainless that is somewhat to be expected as stainless is a little harder to machine smooth than carbon steel. Thanks for all the opinions. I was pretty sure this would shake out with several slants on how and what to use. I am sure that just shooting a lot of lead conicals will accomplish the same thing over time and is probably safer if you have the time.

RE: JB bore paste
 

MLKeith, you are correct and maybe I should have mentioned that,I sort of assumed it was commenly known, I us JB first and then the finest grade og jewelers rouge. Lee

RE: JB bore paste
 

i was always warned that jewlers rouge can get into the metal pores and stay there while jb is safe and wont embed into the metal. the gunsmith at gander mountain i spoke to will only use jb bore paste.

RE: JB bore paste
 

liquidorange,Never heard of that problem before have been using it for 40 years. Lee

Not true. Been using jeweler's rougeintwo grits for 40 years.

I am fairly new to Mls and I've read alot of posts about JB bore paste.
Before getting into the blackpowder side of things, I only shot and hunted with centerfire and rimfire rifles and pistols, so this is where my experience lies.
One of the things I was taught as a lad in Alaska regarding guns ( by my Grandpop and my Dad) is that they almost considered it a sin to put an abrasive down a rifle barrel. They used bore brushes infrequently and depended on good solvents to eliminate fouling.
Maybe it's that age old Scots/Irish thing about trying to make a tool last a lifetime rather than purchase again. It seems to me that using any abrasive would be the same as a few hundred or a thousand rounds through that barrel, and in doing so, shortens the life of said barrel.
I don't know. I do know my Grandpop wouldn't part with a nickel if he could help it.;)
Not trying to be contentious, just don't completely understand the reasoning I guess.

I guess my question is,... are new muzzleloader barrels that much rougher than a center or rimfire barrel, that it has to be polished before it'll shoot right?

RE: JB bore paste
 

I think if you check there are a lot of people that use the bullets with abrasive on them to break in new centerfire barrels. It sort of depends on what you think is required to "break in" a barrel. In the case of the muzzleloader a lot depends on how the rifle loads which is not part of the centerfire routine. My Omega was a bit#@ to load and polishing with JB made the loading a lot easier. All rifle barrels have some machining roughness remaining. Probably the cut ones are a little worse than the button rifled ones but again it is sort of your decision. As I mentioned before just a lot of shooting solid lead bullets will eventually break in your muzzleloader. Doc White says to not be concerned with how your rifle shoots until the first 200 loads. Thats a lot of shooting for me as I have trouble getting that much range time. With four new rifles last year that means 800 rounds.

RE: JB bore paste
 

I see your point.
For a competitive shooter, or someone concerned with how tight he can get the groups on a target, that makes sense. Every rifle I have ever owned, I can sight in and be happy with out of the box. I never have been concerned with MOA. I'm not exactly the poster boy for benchrest shooting.:D
For you fellas that want to do it, more power to ya. Just can't see it myself.
