My first shot fliers were when using the .440 balls. I have not had any fliers since I switched to .445 balls. With the .445's there is a different problem - the first two or three shots are spot on, then, if I don't clean, and keep firing the shots start spreading. I attribute this to a build up of fouling. IF I wipe after every shot, things are much more consistent. I had stopped for a couple weeks after I got three shots in a row into a quarter. I'm getting ready to go out and continue my testing.
I don't know that much about it; but I don't believe the fouling ever stabilizes; it just keeps building up. At some point you got to clean her out. Now when I was using wet lube I could fire 10-15 shots without wiping; but I never really tried developing an accurate load because I want the same load for range and field. That's why I went to the dry lube system. In the field, if I ever fired more than a shot or two, it is no big deal to run a spit patch through when needed to maintain accuracy.
