Re: Case cleaning routine...
I use a 22 caliber bronze brush with steel wool wrapped around it
the trick is to get it real tight.
The mica is to make the seating smoother which in my tests makes the seating depth much more consistant. It also seems to have slightly reduced my velocity standard deviation although there are so many variables there that I can not say that is the cause.
