Bore polishing to help with fouling: it worked!

Are you supposed to use the scotch brite dry or are you supposed to use an oil or other lubricant when this is done? Watching the video it looks like he used the scotch brite dry.

I did what he did in the video and used it dry. Worked fine for me.

It will definitely be a project to find the best lube and patch. But before I polished this bore, I would challenge anyone to load it after 3 shots, no matter the lube. Just a rough bore, I guess. I remember someone else on here had a similar problem with a GPR awhile back.

Mike is a great source he explains and tests before your eyes. Seeing is believing!

I started and found that I needed to make the pad (Ace metal finishing pad that Mike uses) thinner. I ran two pads through the bore about 30x each. Here is the after process movie. I am hoping someone can describe what I am seeing. Thanks.

You are looking into the chambered breech of your Lyman GPR.

If you play the video, there are white patches and other stuff that I don't know what they could be. I hope people can view the video.
