Slightly off topic, apologies for that, but what shell plate are you using to load 38 S&W in your dillon? I have a buddy that has an old revolver in .38 S&W, and he asked me if I could load for it with my 650, but I wasn't able to find out what shell plate would work.
38 s&w is essentially a shorter 38 special case and I think rim size is very similar.
