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?

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

Brownells carries it also.

Sportsman's Warehouse is where I get mine.

natchez shooters

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
