I ordered mine through Mid South Shooters Supply. The way to use it is make sure the barrel is clean. Then with gun oil on a patch, swab the bore. Now you want tight fitting patches for the next part. Smear the patch with the JB Bore Paste. Up and down is one stroke. Give the rifle 25 strokes and then change patches. In a new rifle, normally 50 strokes is all it takes. Then clean the gun as normal. When you look through it, you can tell us what the bore looks like. It should look like a mirror.
