There is proven facts about not polishing a chamber that point to less load on the bolt. It really does nothing to polish it. I used to test fire after using a new reamer I made like this: Take the extractor off the bolt. Fire a round. Open the bolt and lift the rifle straight up and down. GENTLY tap the stock on the table. The case should easily fall out. Actually, most cases fell out just by picking the rifle up. I mostly used 0-1 tool steel for those hard to find reamers and wildcats. Not the best for a mirror finish, but not too bad either. If you have trouble checking this way, there is more than a finish problem going on.
