On another note, the Vision taught me what this "dreaded crud ring" was that everyone talks about. My 2 CVA's don't have major problems with the crud ring, so it was an unpleasant surprise to find it happening with the Vision. I tried switching to T7 primers, but didn't notice any difference in the crud ring, so I switched back to the Win W209's.
I found that I needed to swab 1 spit patch and 2 dry patches between shots to keep the crud ring manegable.
