I'm shooting a 20 Prac AI, I went this way because its just one pass with a .230 bushing in an "S" die and all I have to do is fire form. I would think that a standard 20 Prac would be the same. Mine shoots 40gr Bergers in one hole at 100yds and almost as good with the 40 Vmax. The velocity's are running neck and neck with my 204's.
