Default Need help.. Jb bore paste

I just finished my rifle stock and stain, so i started cleaning the barrel out and noticed and its in dire need of a good polishing. Can someone tell me how to use jb bore paste? Im going to buy some and polish the bore.

My wet paper towels kept coming out with big clumps missing, so i tooth a flash light and looked down there it needs a really good polishing.

After this stain drys im putting it all together and test firing it tomorrow afternoon.

That other side of the stock that i thought was going to be hard, turned out to be really easy. Just took some elbow grease to get it done.

The way to polish the bore is first, take a clean patch and put a quality gun oil on it. Then swab the barrel good with the oil patch. Next with a tight fitting jag and patch smear some of the JB Bore Paste on that and work the first couple five runs or so, down in short strokes.

Every 15 strokes, add a little more paste onto the patch. On the next set of strokes run the full length of the barrel from muzzle to breech. I like to give 50 strokes. A stroke is all the way down and then back up.

After you have 50 strokes, give the thing a good soap and water bath and then run some solvent patches through it. It should shine like a new dime at this stage. Then dry patch it good, and be sure and put a good oil back in the bore since you stripped the bore of everything.

Their seems to be some confusion, when you use a grinding compound you are lapping the bore [if thats what it really needs nothing less will do] if it only needs polishing the process is the same but you use jewelers rouge or diamond dust polishing compound. Lee

The bore looks like 30 yers worth of lead build up an when i run the patch down there, its tight and you can feel the grit in there.

JB bore paste is a very fine abrasive, nothing like grinding or lapping compound. It would take a lot of passes to remove much metal. I made 200 passes in my stainless Omega and it just brightened up the bore and removed some of the machining roughness. My bore still measures exactly the same as before the JB paste procedure or at least a slug from the bore measures the same as close as I can measure with a dial caliper.

Yes valve grinding compound will work, but you have to understand it is much more abrasive and could remove metal from the barrel if you lapp too much.

Okay, i'll take it easy. Maybe 8- 10 passes with it? I just swabbed it with borebutter cleaning patchs and its not as tight but deff. needs a polishing.

How many passes with the valve lapping compound would you do?

That would depend on the condition of the barrel and what I was trying to accomplish. For just cleaning I would only do 20 passes then clean it and see how it looks.

One rifle I saved for a person took over 100 strokes with grinding compound as I remember, but they had fired it then put it in a basement for three months uncleaned. They were using Pyrodex. I really never thought the rifle would shoot properly but the funny thing is, it still shoots great. I just has to reduce the powder charge a little from what they used to shoot. He gave me the rifle because he figured it was junk.

Okay thanks for the help. I'll go ahead and use that compound tomorrow before i shoot it. By the looks of this front sight i have on it, i better take my file outside with me when i go to shoot .. This sight looks like is was made for close range.
