Home Forums Hunting & Shooting Gunsmithing Winchester 100 chamber

I've used 1200 before - in fact, I've used 2000 a couple times.. But that was when I was polishing a shotgun barrel in prep for hot bluing.. The customer wanted a shine he could see his face in..

But on a chamber, 500 is about as fine as I'll ever go. 400 will polish any S/A chamber in order to give proper function..
