You guys really need to try swabbing with pure 91% alcohol. Start with apatch that's a little wetter than what you normally use. And don't worry about the charge getting wet. That stuff drys fast, especially when the barrel is warm.
I went to pure alcohol about 2 months ago. I highly recommend it as well.Someone on here I think said that they were using it to clean BH so I gave it a shot. That's when I found that it not only works well for BH cleanup but great for swabbing between shots. When I was using a 50/50 mix of alcohol and windex it would take two dry patches afterward to get it dry. Now I don't have to worry about that. One side of a dry one is about all it takes. But it's warmer her in TN that where some of you guys are.
As far as seating pressure goes, I've seen it cause all kinds of accuracy issues before. I lean on mine every load, every powder, every shot. That way I know that there's no difference from shot to shot.
