I have had a 6PPC for more than a couple of decades. I absolutely don't like tight patches because they squeeze the solvent into the chamber instead of carrying it into the bore. For that reason I use a .22 CF piercing style jag, with 1 3/8" sq . cotton flannel patches. These days, no serious shooter should be without a bore scope. I have one of the more expensive variety, but you are in luck. Today there is Teslong (amazingly inexpensive). Several of my friends have them. They work great and because you are viewing a digital image, or video, you will have a file that can be emailed. This has been the key for me being able to help a couple of fellows with accuracy issues that have turned out to be cleaning related. If you think that bronze brushes might be optional, and that you can do it all with solvents, you are going to have cleaning issues. I would not have believed it, but one fellow that I know found that his entire throat and several inches of bore are heavily coated with hard carbon, and getting that out is a huge problem. For the record, cleaning every 30 rounds or so, shooting mostly 133, I have been able to keep my barrels clean and carbon free using Butch's Bore Shine, patches and bronze brushes, nothing more. Other powders have different cleaning requirements. One of the fellows with the biggest problem kept using the same brush. In benchrest we buy them from specialty suppliers by the dozen and toss them frequently.
