Do any of you guys or gals use JB compound or any other agent to polish the bore of your BP rifle ?

I have always polished the bore of new to me rifles either using JB bore paste or green scotch brite patches.

I just acquired a GM drop-in barrel for a TC, it was cutting patches, I could only get a 5" group out of it at 50 yards. I used a oiled green scotch bright patch with 50 strokes, followed by a patch saturated with JB bore paste and 100 more strokes. I haven't tested the gun yet but the previous barrel I treated this way went from 5" groups to a 1" group at 50 yards and stopped cutting patches.

On all the ML rifles I build or own I run 4/0 steel wool down the bore 25 to 50 times before I use them on a build. After the gun is built and before it is shipped I will do this process again but only about 10 times and give the bore a LIGHT coating of a GOOD gun oil on a clean patch. Works for me.

Has anyone used automobile compound on a tight patch? You can get two different grits and it works well.

I have but only one gun that I own has needed it. It was literally destroying patches. It helped allot. I fire lapped the barrel also some.

IMHO, 0000 steel wool wrapped around a cleaning jag is what I use on a new barrel. I usually am listening to tunes on the radio while working in my shop. When it comes time to treat a new barrel, if a known long song starts, I will run the steel wool in and out of the barrel during the length of the song.

I use toothpaste on a bronze bore brush to clean the oil out of new barrels, Automotive buffing compound to lap lightly pitted bores, and lapping compound and lead slugs on badly pitted bores. I have also used the scotchbrite to clean out bores that have been "seasoned".

Just curious how you get a green scotch brite pad down the bore? On a wrap around jag? Or a slotted patch jag?
Thanks

Use the next size down cleaning jag with cut to length pad wrapped around it. Tight fit but that's what you need.

I use 0000 for new barrels. The number of strokes depends on the tooling marks in the barrel. I use a bore scope to check out the barrel. I have tried the green and red pads but they don't cut as well in a barrel as the 0000. The steel wool can be wrapped on the brush to make it very tight as needed.
I use JB paste to scrub out the barrel preservative in factory rifles like the Lyman GPR. Almost everything coming from abroad has that stuff in the barrel. I learned to remove this coating when coaching kids air rifle teams. Most bore cleaners won't touch it. Do to color lots of folks confuse it with rust.

Years ago I purchased from Brownells I believe it was, something called Ground Ruby Bore Polishing Compound. Gets the job done real quick. The label has long since fallen off the bottle so I can’t give you any more specific information about it.

A maroon scotch bright pad will remove a lot of metal, I would go with green as well.

I cut my green patch to about 1" square( I start bigger and keep trimming until it will fit), and am pretty sure I use a .45 jag in a .54 barrel.
